**PLEASE NOTE THE ADDRESS CHANGE! We're now at [w3hub.berlin](https://w3hub.berlin)** [Qase](https://qase.io) is presenting the **twelfth** Meetup on Quality Engineering in Berlin. As usual, we’re bringing you three deep-dive talks, **but also something extremely new and exciting — food testing activity. Don't worry, we won't be the test subjects, we will feed the spectrometer and see if our tests pass or fail :)** **AGENDA** **1\. Sebastian Kasanmascheff\, CEO/Owner @ Altum Solutions:** ***Wetware QA Jumpstart: Hands-On Spectrometer Demo*** Did last meetup’s “Food QA: Testing Tasting” session whet your appetite for wetware testing? Well here is an invitation to turn theory into practice with a live showcase of the device that taste-tests like a human, namely, the spectrometer. Take a leap from the familiar realms of software and hardware into the exotic world of wetware: translate between computer bits and chemical bonds, complement your programmer hoodie with a lab coat, and let us test what is in our food: \- How much protein is really in your protein powder? \- Can you trust the fat content values on your milk packaging? \- What ingredients are hiding in your favourite fast food meal? Learn how to answer such questions by joining the Altum Solutions team for an end-to-end spectroscopy workflow: from sample preparation to ML/AI-enhanced scientific analysis. This same wetware QA pipeline empowers sustainable lab automation across Big Food, AgriTech, and Pharma 4.0. **BYOB — Bring Your Own Bytes/Bites** **2\. Jaideep Naik\, Senior Software Engineer: *The Migration Hell: From Ghost Inspector to Cypress*** Jaideep will share his lessons from a 12-month test automation migration from Ghost Inspector (low-code) to Cypress (code-first). Limited planning led to flaky tests, slow CI pipelines, and lost trust in automation. Covers the key challenges — skills gap moving to JavaScript, tightly coupled tests, inefficient Page Object Model, UI-based auth bottlenecks, static test data, no coding standards — and the solutions that fixed them: phased migration, page-based POM with standardized locators, API-based auth, dynamic test data, and PR reviews from the start. **3\. Radik Zagirov\, Founder @ Agentiqa: Quality Is Binary: Why Your Coverage Metrics Don't Matter After the First Escalation** Radik argues that shipping code has become essentially free — AI writes code, CI/CD deploys it. But quality hasn't kept up. The bottleneck has shifted to people and processes, and business perceives quality as binary: everything works, or QA failed. One escalation erases months of coverage improvements and process building. Radik will share his understanding, that the answer isn't better testing but rather better communication. How to explain QA's value in the language of money, risk, and speed, and how to build "opportunity tunnels" — systematic channels that make QA's impact visible before an incident forces the conversation. **4\. Anupam Krishnamurthy\, Head of AI Testing @ TestSolutions GmbH:** **Ensemble Testing of an LLM Application** Earlier in November, Anupam demonstrated how we could test LLMs by using the LLM-as-a-judge approach. In that session, somebody asked, how can we trust an LLM to judge another LLM? In this session, we put LLM judges to the test. We'll do some live testing to have an LLM judge evaluate an existing RAG application. We'll then put up the results on the big screen and take a look together, to verify if our LLM judge is working as expected. In other words, everybody in the room will judge the judge. Can an LLM judge survive the scrutiny of a hundred pair of expert eyes? Come and find out in this live ensemble testing session.

**💶 Wertschätzungsbeitrag: 10-20 Euro (nach eigenen Möglichkeiten)** **Du möchtest Deine Freundschaften, Partnerschaft & Arbeitsbeziehungen verbessern? Dieser Worskhop kann ein großer Schritt dazu sein.** Beziehungs- und Bindungstypen sind ein weit verbreitetes Modell, um typisches Verhalten in verschiedensten Beziehungen erklären. Warum klammert jemand? Warum Drama? Warum Rückzug? Warum Kälte? Warum Unsicherheit, Nervosität und Ärger? --- und wie sieht eine sichere & gute Beziehung aus (und fühlt sich an). Die Annahme: Ereignisse der frühen Kindheit & der Erziehungsstil unserer Eltern prägen, wie wir als Erwachsene unsere Partnerschaften, Freundschaften & Arbeitsbeziehungen leben. Für manche gut. Für manche weniger gut. Ich setze mich mit den Beziehungstypen auseinander, weil ich glaube, dass sie einen wesentlichen Einfluss auf die Gestaltung von Freundschaften haben (und auf Liebesbeziehungen sowie menschliche Beziehungen jeglicher Art). Dabei habe ich entdeckt, dass ich oft einen vermeidenen Beziehungsstil habe - ich weiche lieber aus, trenne mich oder spreche Probleme nicht an, weil ich wahrscheinlich in meiner Kindheit aus unterschiedlichen Ereignissen gelernt habe... dass bringt eh nichts, ich kann anderen nicht vertrauen, das macht man nicht, meine Bedürfnisse sind nicht wichtig, usw. In der Auseinandersetzung mit den Beziehungs- / Bindungstypen habe ich bemerkt, wie gut es mit tut, mit anderen mich darüber auszutauschen. Weil: * Ich bin nicht allein. * Ich lernen die Gefühle anderer kennen * Ich entwickle ein gutes Gefühl für die anderen Beziehungsstile (nicht nur meinen) * Ich löse das Thema für mich Schritt für Schritt - und werde immer sicher in meinen Bindungen & Beziehungen. In eine Workshop-Beschreibung zu schreiben, dass ich mich oft beim vermeidenden Beziehungsstil entdecke... ist kein Vermeiderverhalten mehr 😊. Halleluja! . **🎁 Das kannst erwarten** Ich lade Dich zu diesem Workshop ein, damit Du einen weiteren Schritt Richtung mehr Leichtigkeit & Ehrlichkeit in Beziehung gehen kannst. Ich werde eine kleine Einführung zu den Bindungsstilen geben - und dann steht der Austausch miteinander im Mittelpunkt: * Was sind Situationen, die mich triggern? * Wie geht es mir dann? * Wie reguliere ich mein Nervensystem? Meine Erfahrung ist: Austausch & Offenheit hilft, mit sich selbst und anderen relaxter zu werden. . Ein Link oder ein Buch zur Vorbereitung findest Du weiter unten. Es wäre gut, wenn Du eines von beiden bereits gelesen hättest oder von anderer Seite Vorwissen zu den Bindungstypen / Beziehungstypen hast. . . **⏰ Die Türen sind offen ab 18:15 Uhr. Komm am besten schon 18.15 Uhr** Mantel aufhängen, Toilette, eine Runde schwatzen und los ... . **❓ Darf ein zweites Mal kommen?** Ja, sehr gern. Ich halte es sogar für sinnvoll, mehrfahr zu kommen, wenn Dir der Workshop gefallen hat: Das Thema vertiefen, die eigenen Beobachtungen aus den letzten Wochen verarbeiten und sich mit neuen & alten Bekannten über das Thema weiter austauschen. 💬 **Agenda** 18:15 Uhr - Doors Open & Ankommen 18:30 Uhr - Start des Workshops * Einführung, Vorstellung * Kleines Kennenlernen * Einführung in das Thema durch mich * Verständnisfragen * Verschiedene Austauschrunden mit Vertiefungsfragen (der größte zeitliche Anteil) * Offene Fragen 21:30 Uhr - Ende . Zwischendurch machen wir eine kleine Pause. . Tausche Dich mit Gleichgesinnten über ein wesentliches Thema Deines Lebens aus. Du kannst immer wählen, mit wem Du Dich in welcher Tiefe unterhalten möchtest. Dein Gegenüber natürlich auch :). Nein heißt nein, Ja heißt Ja 🤗 . **🏠 Der Veranstaltungsraum** * Wir haben einen wunderschönen Raum im Kieztreff in Berlin Mitte (mit sauberen Toiletten!). * nähe Hackescher Markt. Sehr gut mit den Öffis zu erreichen. * Wenn Du vor Ort ankommst, ist alles ausgeschildert. . **🎒 Das bringst Du mit ...** * Etwas zu trinken (z.B. deine Wasserflasche, keinen Alkohol!) * Wenn Du magst: Zettel und Stift. * Du solltest satt sein und vorher gegessen haben * Bargeld für den Wertschätzungsbeitrag (10-20 Euro) . 📋 **Kann ich mich vorbereiten?** Ja! Vielen Menschen sind die Beziehungstypen bekannt. Wenn Du etwas Grundwissen hast, ist das sehr nützlich für den Workshop. Ansonsten empfehle ich diesen Link zu lesen: Link: [Welcher Beziehungstyp bin ich?](https://chrisbloom.de/blog/welcher-beziehungstyp-bin-ich-mit-test/) Dieses Buch ist eine sehr gute Einführung in den Workshop. Der Workshop wird sich daran orientieren: * **[Buch: Warum wir uns immer in den falschen verlieben](https://amzn.to/498A9js) (Werbung, Amazon-Link)** [Werbung: Als Amazon-Partner verdiene ich an qualifizierten Verkäufen.] Das Buch orientiert sich an Liebesbeziehungen, die Erkenntnisse sind meiner Meinung nach aber auf alle menschliche Beziehungen anwendbar. 🚫 **Was ist der Workshop nicht:** Der Workshop ist kein therapeutisches Angebot. Dafür bin ich nicht ausgebildet (bisher noch nicht mal im Selbststudium). Wenn Du aufgrund der Erkenntnisse beim Lesen des Buches, der Links oder der Gespräche auf dem Workshop zum Ergebnis kommst, dass eine Therapie für Dich sinnvoll sein kann, dann wäre das ein richtig guter Schritt. . 💫 **Warum der Workshop gut für Dich ist** * Ich glaube: Niemand ist perfekt. (und gleichzeitig deshalb genau richtig 🙂) * Ich glaube, dass jeder in wenigstens minimaler Form manchmal Arten von unsicheren Bindungsverhalten zeigt * Gleichzeitig wird jeder im Leben mit Menschen zu tun haben, die ein unsicheres Bindungsverhalten zeigen. . Mit sich selbst und anderen reflektiert umgehen zu können, finde ich eine zentrale Fähigkeit im Leben. . Ich finde, dass gute menschliche Beziehungen sind der zentrale Schlüssel zu einem erfüllten Leben sind (das finden laut Jacobsstudie übrigens 85 Prozent der Menschen in Deutschland). . Die Bindungstypen / Bindungsverhalten sind meiner Meinung nach ein zentrales Modell, um gute menschliche Beziehungen führen zu können. . 🧑🏼 **Mehr über mich:** Ich forsche seit 5 Jahren zu guten Freundschaften, wie man diese aufbaut und vertieft.

Join our in-person meetup on April 24th to hear talks from experts on cutting-edge topics across AI, ML, and computer vision. **[Register to reserve your seat.](https://voxel51.com/events/berlin-ai-ml-and-computer-vision-meetup-april-24-2026)** Space is limited! **Date, Time and Location** Apr 24, 2026 5:30 PM - 8:30 PM [MotionLab](https://motionlab.berlin/) Bouchéstraße 12/Halle 20 12435 Berlin **Kaputt: A Large-Scale Dataset for Visual Defect Detection** We present a novel large-scale dataset for defect detection in a logistics setting. Recent work on industrial anomaly detection has primarily focused on manufacturing scenarios with highly controlled poses and a limited number of object categories. Existing benchmarks like MVTec-AD (Bergmann et al., 2021) and VisA (Zou et al., 2022) have reached saturation, with state-of-the-art methods achieving up to 99.9% AUROC scores. In contrast to manufacturing, anomaly detection in retail logistics faces new challenges, particularly in the diversity and variability of object pose and appearance. Leading anomaly detection methods fall short when applied to this new setting. To bridge this gap, we introduce a new benchmark that overcomes the current limitations of existing datasets. With over 230,000 images (and more than 29,000 defective instances), it is 40 times larger than MVTec and contains more than 48,000 distinct objects. To validate the difficulty of the problem, we conduct an extensive evaluation of multiple state-of-the-art anomaly detection methods, demonstrating that they do not surpass 56.96% AUROC on our dataset. Further qualitative analysis confirms that existing methods struggle to leverage normal samples under heavy pose and appearance variation. With our large-scale dataset, we set a new benchmark and encourage future research towards solving this challenging problem in retail logistics anomaly detection. The dataset is available for download under [https://www.kaputt-dataset.com](https://www.kaputt-dataset.com). *About the Speaker* [Sebastian Höfer](https://www.linkedin.com/in/sebastian-h%C3%B6fer-891178121/) is an Applied Science Manager at Amazon Fulfillment Technologies & Robotics, leading machine learning and computer vision research for large-scale robotics and warehouse automation. He received his PhD from the Robotics & Biology Lab at TU Berlin, focusing on Sim2Real transfer and robotic perception. His recent work, “Kaputt: A Large-Scale Dataset for Visual Defect Detection” (ICCV 2025) [37], established a major benchmark for industrial anomaly detection, reflecting his expertise at the intersection of academic research and real-world deployment. **Data Foundations for Vision-Language-Action Models** Model architectures get the papers, but data decides whether robots actually work. This talk introduces VLAs from a data-centric perspective: what makes robot datasets fundamentally different from image classification or video understanding, how the field is organizing its data (Open X-Embodiment, LeRobot, RLDS), and what evaluation benchmarks actually measure. We'll examine the unique challenges such as temporal structure, proprioceptive signals, and heterogeneity in embodiment, and discuss why addressing them matters more than the next architectural innovation. *About the Speaker* [Harpreet Sahota](https://www.linkedin.com/in/harpreetsahota204/) is a hacker-in-residence and machine learning engineer with a passion for deep learning and generative AI. He’s got a deep interest in VLMs, Visual Agents, Document AI, and Physical AI. **Most AI Agents Are Broken. Let’s Fix That** AI agents are having a moment, but most of them are little more than fragile prototypes that break under pressure. Together, we’ll explore why so many agentic systems fail in practice, and how to fix that with real engineering principles. In this talk, you’ll learn how to build agents that are modular, observable, and ready for production. If you’re tired of shiny agent demos that don't deliver, this talk is your blueprint for building agents that actually work. *About the Speaker* [Bilge Yücel](https://www.linkedin.com/in/bilge-yucel/) is a Senior Developer Relations Engineer at deepset, helping developers build agentic AI apps with Haystack. Passionate about AI, she makes complex concepts approachable through hands-on tutorials, both online and at real-life events. **Operationalizing Computer Vision for Overhead Lines: Beyond the Demo** At first glance, visual inspection of high-voltage power lines seems straightforward: collect imagery, run one or two AI models, and report the findings. In practice, moving beyond a proof of concept reveals a range of issues that can make or break a campaign. Common concerns include data quality and coverage, scarcity of the most relevant cases and abundance everywhere else, variations in pylon geometry and asset types across regions, calibration and GIS alignment challenges, and a long tail of edge cases that emerge in real-world operations. This talk introduces Siemens Energy’s end-to-end overhead line inspection solution and shares key learnings from inspecting more than 10,000 km of power lines for real customers across several continents. We will show how raw 2D/3D data is transformed into structured information, delivering insights into asset inventory as well as defects, and supporting maintenance and planning decisions for critical infrastructure. The focus is on the combination of algorithmic building blocks and scalable processing, designed for robustness and consistency at scale, where even low error rates can become operationally significant. *About the Speaker* [Stefan Wakolbinger](https://www.linkedin.com/in/stefan-wakolbinger-aa0ba874/) is the Development Team Lead for AI & Analytics at SIEAERO, Siemens Energy's digital powerline inspection service. He leads the development of cutting-edge AI and analytics solutions that transform aerial powerline inspection through multi-sensor technology. His team creates digital twins of powerline infrastructure, automates fault detection, and monitors vegetation management—making powerline inspection safer, more precise, and more efficient. Stefan has been driving innovation in this role since September 2022. **Search your video library like a database** Drop in YouTube URLs or upload files and query content four ways: exact keyword matching, semantic search across transcripts, visual scene search via SigLIP2, and LLM-generated answers that synthesise across segments.

We are back in the c-base! Do you already run NixOS and want to talk to other people or want an introductory session with some NixOS users. Just bring your machine! Usually there are no topics, we just sit in front of our computers, talk about stuff, debug some problems or review some PRs on nixpkgs. There are drinks usually available from the c-base bar. If you can't find us. just ask around or ask in irc (#krebs on hackint)

Hello fellow Symfonians, we are thrilled to announce the next user group meeting of the year, featuring two insightful talks that you **won't want to miss**! This time we are hosted by c-base (Rungestrasse 20 10179 Berlin). Come by and enjoy an evening of learning, networking, and socializing with fellow Symfony and PHP developers. **Agenda:** 18:30: Doors open 19:00: Welcome and Introduction 19:20: **Talk 1: "Maintainable Frontends for Symfony" by Daniela Berger** 19:50: Break & Snack 20:00: **Talk 2: "Why every CMS needs MCP" by Roland Golla** 20:40: Socializing **Talk Details:** **Talk 1: "Maintainable Frontends for Symfony" by Daniela Berger** In many web projects we find more backend devs than frontend devs, sometimes significantly so. This often leads to devs with little frontend experience being asked to do frontend development anyway, and they often end up shaping their frontends in ways that will make their lives unnecessarily hard. One common result are frontends that are functionally unmaintainable because each change - whether it is a new feature or a bugfix - requires implementing an exception to existing code, thus making the code increasingly and unnecessarily complex. This is especially upsetting because with a bit of experience it is possible to implement light-weight frontend components with equally elegant CSS and JavaScript that are easy to extend and to adapt to new requirements without digging oneself into a deeper hole with each PR. And since Symfony is making frontend development steadily more accessible to backend devs with Symfony US / Stimulus, this is a good time to take a closer look at \*how\* to structure these frontends. This talk aims to a) introduce core frontend concepts that backend devs might not be aware of, b) show best frontend practices both on the code level and on the architecture level, c) show a few common mistakes that can be found in inexpertly implemented frontends, and c) introduce tools that will make consistent frontend development easier. **Talk 2: "Why every CMS needs MCP" by Roland Golla** Your content team already works in ChatGPT, Claude, and Gemini. Yet the content still lands in the CMS backend manually, clumsily, slowly. MCP changes that. One sentence in chat becomes a published article. No copy pasting, no formatting, no clicking. And the content ranks. On Google, on ChatGPT, on Perplexity, on whatever comes next. Good content written by AI directly into the CMS goes live faster and gets found. I show you the MCP plugin for Sulu CMS: open source, built on Symfony, ready to deploy. But this is not about implementation. It is about the three questions every content team must ask: Why does every website need MCP? What does good AI content look like? And why is conversational content management better than anything you click together in a backend? MCP makes content creation as easy as chat. If you can write, you can publish. No CMS training, no workflow, no waiting. Live on stage: a complete workflow from idea in chat to published article in Sulu CMS. Everything open source on GitHub. Don't miss these insightful talks, engaging discussions, and networking opportunities. We can't wait to see you at the **April Symfony User Group**!" If you have any questions or accessibility requirements, please reach out to us. Also, if your company wants to be the next host for the User Group, just let us know!

Abstract We ran everything in one Azure subscription. Leads and sales, installations and steering energy systems. Everyone had access. Most resources were created manually. It was unclear who owned what. As the tech org grew from 100 to 300 people, reinventing security and scaling individually stopped working. We'll cover how we approached platform building as gardeners rather than architects: observing what already works, replicating it, and letting rituals emerge before encoding them. We'll look at some mistakes we made along the way and what we learned from each. *Dayana Mick* **It works… but no one understands it: The hidden problem in DevOps** For several years, I kept asking the same question to senior developers, staff engineers, and mentors: “What is a build?” I rarely got a clear answer. Not because people didn’t know, but because the mental model had faded somewhere between Terraform, Ansible, Kubernetes, and “just run this command.” At some point, I realized I could run pipelines, deploy services, and fix things just enough to move forward, but explaining what was actually happening was much harder. And I was not the only one. This talk is about a pattern I’ve seen across every company I’ve worked at. Systems that work, but are not really understood. Teams running platform commands from memory. Platform teams becoming bottlenecks. Incidents where even experienced engineers hesitate. And situations where people rely on tools without a clear sense of what is actually happening underneath. With AI, this is only accelerating. This is a talk for anyone who has ever copy-pasted a command, watched it work, and decided not to ask further questions. It is especially relevant for junior and mid-level engineers navigating DevOps complexity, and for teams who are trying to scale tooling without losing shared understanding.

NOVA Code and Coffee is an inclusive, informal, co-working session. People of all skill levels are invited. The concept is simple, bring a laptop and ideas, we'll provide the coffee and donuts! Here's how it works: 1. At 10:15 everyone introduces themselves and briefly describes what brought them to Code & Coffee today (project, homework, networking, etc) 2. For the rest of the day, folks work in the communal space on their projects providing one another help and conversation as needed. Oh and they usually drink coffee and tea too! That's it! Hope to see you there! **Location** Our hosts are the Fairfax City Economic Development Building: [10300 Eaton Pl, Fairfax, VA 22030](https://www.bing.com/ck/a?!&&p=d7298231ca2df594df822003f9a93517c788fceefe1fcbb79c8976696e341bc6JmltdHM9MTc1MzIyODgwMA&ptn=3&ver=2&hsh=4&fclid=180d0745-3b7f-69a1-23a2-11433a7868e5&u=a1L21hcHM_Jm1lcGk9MTA5fn5Ub3BPZlBhZ2V-QWRkcmVzc19MaW5rJnR5PTE4JnE9RmFpcmZheCUyMENpdHklMjBFY29ub21pYyUyMERldmVsb3BtZW50JnNzPXlwaWQuWU44NzN4ODI4MTk2Mjg0NTk5MDM4MTU0MiZwcG9pcz0zOC44NjE0NDYzODA2MTUyMzRfLTc3LjMwMjE3NzQyOTE5OTIyX0ZhaXJmYXglMjBDaXR5JTIwRWNvbm9taWMlMjBEZXZlbG9wbWVudF9ZTjg3M3g4MjgxOTYyODQ1OTkwMzgxNTQyfiZjcD0zOC44NjE0NDZ-LTc3LjMwMjE3NyZ2PTImc1Y9MSZGT1JNPU1QU1JQTA&ntb=1) Conference Room A- Large, Floor 1 This is a new venue for us, so give us some time to get more details about it.

Kim Richey is one of my top favorite musical artists. I have been a fan of her music since the late 90s. She is also a sweetheart and a pleasure to chat with. I have seen Kim Richey with two musicians (herself included), three musicians and with a full band in Nashville and I am always impressed on how terrific the concerts are. She is scheduled to play at Jammin’ Java on May 10th. The ticket link is below. Here are a bunch of songs I selected from her first three CDs (my favorite CDs of hers. Every track on every CD is a gem). She draws a lot of her concert songs from those CDs. [https://www.youtube.com/watch?v=7MjBb_2WOys&list=PLG-Pcqm-1YXhs1rt8HO_A0jSlnTggUrUP](https://www.youtube.com/watch?v=7MjBb_2WOys&list=PLG-Pcqm-1YXhs1rt8HO_A0jSlnTggUrUP) The first time I saw her was at Jammin’ Java (which is a nice little venue, btw). We chatted after the show. It was like chatting with an old friend. I asked her about playing with a full band. She told me that she will have a full band in Nashville. I gave it a bit of thought and told her that I have family in Clarksville (about an hour from Nashville). As we parted company, I was about 20 feet away from Kim when she shouted out to me, “Hey Felice!” (I introduced myself to her with my birth name). “I’ll see you in Nashville!”. I looked at her and said something like, “I guess I \*have\* to go now”. 😊 And I did. My second Kim Richey concert and that was a blast, and I got to see a bit of Nashville. I also met the multi-talented, Sav (“as in Savage”, she said to me) and I learned of her wonderful band, The Accidentals. I live for serendipity. Jammin’ Java is a small venue. You select your seat from a chart. Food and drinks are served. They have delicious pizza! My seat is at Table F. Right now, there are several seats available at my table. GA seats are not at tables.

Spec-driven development flips the traditional workflow on its head: instead of code being the source of truth, the specification becomes the backbone of design, collaboration, and delivery. In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects.
