Smalltalk

Meet us for in-person talks at Zalando on April 28, 2026! Join us for an evening exploring how GenAI is transforming modern engineering — from low-code feature engineering and research workflows to agent-driven optimization and production ML systems. Please make sure you register with your full name, as it will be checked by security on arrival. *** 📅 **Date and Time:** Tuesday, April 28, 2026 Doors open: 17:30 Talks start: 18:00 Panel discussion: 19:20 Networking & pizza: 20:00 *** 📍 **Location:** Zalando Office BHW Warschauer S-Bahn, Auditorium Cinema *** 📝 **Agenda:** **17:30 – Doors Open** Welcome, pizza, and networking **18:00 – Research Harness Engineering for Model Development** Florian Hönicke — Elastic Every programmer is now a manager of coding agents — but human oversight quickly becomes the bottleneck. Florian will share how Elastic built an agentic research harness to support their v5-omni model development, enabling structured experimentation and faster iteration cycles in applied AI research, and why building your own harness is the key unlock for teams serious about scaling agentic workflows. *** **18:20 – Low-Code Feature Engineering in Zalando with Agentic Support** Ola Wahab — Zalando Feature engineering at scale has traditionally been a high-friction process — days of infra setup, complex tooling coordination, and lots of boilerplate. Ola will walk through how Zalando is shifting to a low-code, configuration-driven approach where teams define pipelines declaratively, and how agentic coding has compressed the journey from feature discovery to production from weeks to days. *** **18:40 – Ranking Logic Migration from Monolith — Using Code Agents for Iterative Performance Benchmarking** Ivan Potapov — Zalando How Zalando’s Search and Browse Discovery team extracted a latency-critical ranking service from a monolith and validated it for production. This talk covers: * Migrating the ranking read path into a standalone Ranking API * Using AI-powered agentic loops with async-profiler to close the p99 latency gap * Practical lessons on allocation profiling, virtual threads, and production validation Format: 20 min talk + 10 min Q&A *** **19:00 – Coding Agents for ML Pipelines & AI Systems (Hopsworks + Claude Code)** Jim Dowling — Hopsworks Coding agents are rapidly reshaping software and ML engineering. This talk explores how prompt-driven development is changing how we build ML systems. We’ll cover: * ML problem decomposition and architecture optimization in an agent-driven world * Data-driven experimentation workflows * Building faster and higher-quality systems with Claude Code * Why building on top of AI infrastructure boosts productivity Based on Jim’s O’Reilly book: *Building AI Systems with a Feature Store* Format: 20 min talk + 10 min Q&A *** **19:20 – Panel Discussion** **Product Mindset in Engineering — The Evolution of the AI Engineer Role** Jim Dowling — CEO, Hopsworks Leela Sharma — Director of Engineering, Zalando Florian Hönicke — Principal AI Engineer, Elastic Alexey Grigorev — Founder, DataTalks.Club A discussion on how GenAI is reshaping engineering roles, expectations, and the shift toward product-oriented thinking. *** **20:00 – Pizza, Drinks & Networking** Wrap up the evening with food, drinks, and conversations with fellow engineers and speakers. *** Invite your friends and join us for an evening of learning and networking!

Dear Kotlineers, After a slightly longer break than planned - we are back! This time we meet in the chambers of **voize GmbH** \- one of Berlin's \(if not the\) most flourishing startups\. As the flowers open and the days stretch long, we're dancing into May with some talks. **Line-Up:** 👉 **Coroutines behind the scenes** by *Sergey Shkurov* Have you ever wondered how Kotlin coroutines actually work under the hood? In this talk, we dive into the JVM bytecode behind suspend functions and reconstruct the state machines step by step. You’ll follow a hands-on exploration of real compiled code and see how continuations and suspension actually work. 👉 **YOUR TOPIC HERE** by *TBD* **Speaker Bios:** 🗣 *Sergey Shkurov* A Kotlin enthusiast since 2019. 🗣 *YOUR NAME HERE* TBD

Bitte via Mail anmelden: anmeldung@gedoplan.de **Referent:** Martin Boßlet, Berater, Dozent und Softwareentwickler **Datum und Uhrzeit:** Donnerstag, 30.04.2026, 18:00 – ca. 19:30 Uhr **Ort:** Online mit Zoom Seit zwei Jahren reden alle über KI-gestützte Entwicklung - und vieles klingt gleich: Gestern war Prompt Engineering der Beruf der Zukunft, heute ist es Context Engineering. Claude Code gegen Codex, GitHub Copilot vs. Cursor, Tool-Vergleiche hier und da. Die Älteren unter uns werden sich mit einem Schmunzeln an Vim vs. Emacs erinnert fühlen. Während CEOs bis hin zum Digitalminister den Untergang der programmierenden Zunft ausrufen, wenden sich viele Entwickelnde frustriert ab. "Das ist nichts für mich" - diesen Satz hört man oft. Die Branche scheint sich in zwei Lager zu spalten: auf der einen Seite diejenigen, die KI fast schon aus Trotz konsequent ablehnen, auf der anderen KI-Propheten, die zumindest der Erzählung nach ihren kompletten Alltag mit KI bestreiten und der Konkurrenz schon längst meilenweit voraus sind. Die eigentliche Frage lautet: Warum gehen die Erfahrungen so weit auseinander? Die These dieses Vortrags: Der Engpass liegt meist weder im Modell noch im nächsten "Tool du jour", sondern in fehlendem, verstreutem oder nur implizit vorhandenem Kontext. Der Schlüssel zu erfolgreicher KI-Zusammenarbeit liegt deshalb nicht in besseren Tools oder clevereren Prompts, sondern in der ältesten Technologie der Menschheit - Sprache. Genauer gesagt: in Markdown als universeller Schnittstelle zwischen Mensch und Maschine. Anhand von Architecture Decision Records (ADRs), Mermaid-Diagrammen, **[AGENTS.md](https://www.linkedin.com/safety/go/?url=http%3A%2F%2FAGENTS%2Emd&urlhash=jh-H&mt=F7bnie71WnYrGR3aD-BiSMeaQCiWniKDxaG65SbBgq37lq5u7OZ1P6NjRp-YTlrvhyBy30Lf47AWfYCmtVLwNg99MBUc-2e8qYUzQLXNViKKD4LeW5gizS3yWw&isSdui=true)**-Datei und Agenten-Skills zeige ich, warum Text-First Development kein Retro-Trick ist, sondern ein praktikables Arbeitsmodell für die KI-Ära. Wer Architektur, Entscheidungen und Konventionen in Text statt in Tickets, Chat-Verläufen oder auch nur an der Kaffeemaschine festhält, bekommt bessere KI-Ergebnisse, mehr Präzision und weniger Nacharbeit. Und ganz nebenbei entsteht endlich wieder etwas, das in der Softwareentwicklung jahrzehntelang zu teuer war: aktuelle, brauchbare Dokumentation für Mensch und Maschine. Kein Talk über Prompt-Hacks, Tool-Vergleiche oder das Tool der Woche, sondern über eine einfache, praktische Frage: Wie müssen wir Software bauen, damit KI-Unterstützung nicht nur beeindruckend wirkt, sondern dauerhaft nützt? Die Antwort ist überraschend einfach: kein Tool-Zirkus, kein Hokuspokus. Einfach nur Text. Nach Ihrer Anmeldung schicken wir Ihnen den Anmeldelink zu.

**Relax. Connect. Create. ☕** After a full week of work, meetings, study sessions and life in fast-forward, it’s time to slow down. Join us this Saturday afternoon in Berlin for a relaxed coffee hang-out where this week's agenda is good company & warm drinks. You're also invited to bring some boardgames, drawing/coloring materials (I will bring an adult coloring book) **What’s the plan?** We’ll meet in a cosy spot, draw, chat about everything and nothing, swap stories and simply enjoy the moment. No pressure. No formalities. Just a bunch of friendly people sharing a Saturday coffee. **Who’s welcome?** Everyone! Whether you’re a Berliner born and raised, newly arrived in the city, from Germany or abroad, if you like meeting open-minded folks and spending some relaxed time—come join us. **When & how?** Saturday afternoon. Detailed time and place in our Telegram group. ➡️ Join us on Telegram: [https://t.me/berlinsaturdaycoffee](https://t.me/berlinsaturdaycoffee) Hop in, say hello, and we’ll share the final details. **Why join?** * Because you deserve a break. * Because you enjoy being creative. * Because you enjoy boardgames * Because meeting new people sparks fresh energy. * Because coffee tastes even better when shared. * Because Saturday afternoons were made for this. Respect and Safety: There is always at least one organizer present at every meetup. If you ever feel unsafe or bothered by someone’s behavior, you can reach out to an organizer privately. Your identity will remain confidential, your concern will be taken seriously, and no inappropriate behavior is tolerated — anyone making others feel uncomfortable will be removed from the group immediately. We hope to see you there. Bring yourself, your smile, drawing materials, your stories—or just your comfy self. Let’s make Saturday a little more laid-back, a little more social and a lot more nice. See you soon! —Your Saturday Creative Coffee Crew ☕

Hello everyone, After a great restart last month, we’re happy to invite you to the next Rust Berlin meetup at the JetBrains office. We’ll stick to the classic format: an evening with two main talks, followed by time to connect, discuss, and catch up with the community. Finger food and drinks will be available throughout the evening. **Agenda** * Doors open: 18:30 * Start: 19:00 * Short welcome and updates from JetBrains * 2 talks (20–30 minutes each) * Open mic / lightning talks (optional, a few minutes each) * Networking **Speakers** Egor Lebedev - Welcome and a short note from the RustRover team Till Adam - Slint-MCP In this talk, Till will walk you through the implementation of the MCP server for the Slint GUI framework - and how it's implemented in Rust. He will walk you through the implementation from design to implementation. Gaurav Gahlot - Rust meets Kubernetes This talk is a hands-on walkthrough using kube-rs. We'll connect to a cluster, query pods, watch real-time events via async streams, and build a minimal controller - all in Rust, all running live. **Speaker Bios** Till Adam is the CCO at KDAB and has been working on open-source since the 90s. Originally a C++ company, KDAB has been working with Rust for the last 8 years. One of their biggest projects is CXX-Qt. Their specialization on the Rust side is use in hybrid, high-performance, high-correctness codebases. Gaurav Gahlot is a Software Engineer with experience building scalable platforms with Go, Rust, and Kubernetes. He maintains the CNCF Akri project and actively contributes to open source. **Open mic & future talks** We’ll reserve a few short slots for anyone who wants to share something with the group. This can be a quick idea, a project, or an experience. Slides are optional. If you’re interested in giving a longer talk at a future meetup, this is also a good opportunity to connect with the organizers. **Venue & access** Please arrive on time. We will have someone at the entrance to let people in between 18:30 and 19:15. After that, access becomes more difficult as the doors are locked and require manual opening. **Registration** The venue has limited capacity and events typically fill up with a waiting list. If you register and can no longer attend, even at short notice, please un-RSVP so someone else can take your spot. Looking forward to seeing you all!

Berlin is no longer so dark! Spring has come! 🌷 Let's catch those fresh new rays of sun ☀️. While walking together we can enjoy a nice conversation, get those steps in, increase our serotonin production as well as sync the circadian rhythm. It's also a lovely break from work. I would like to invite you to our mental health walk event. Agenda: 12:10 We meet at Schöneberg Park next to the fountain with the golden deer statue ("Der goldene Hirsch"). 12:15 We walk to Volkspark Wilmersdorf 12:50 We arrive back in Schöneberg Park, at the golden deer statue. We walk at every weather, so make sure to dress properly! Looking forward to meeting you at our lunchtime walk. Marija Please note\*\*:\*\* This gathering is meant for connection and conversation, and is not a replacement for therapy or professional mental health support.

**ℹ️ The next meetups will be managed on Luma.** **You can register for this event 👉 [here](https://luma.com/zma43t8d). Follow the Django User Group Berlin Calendar on Luma.** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-​ In April, we'll be hosted again by [MPB](https://www.mpb.com/de-de?utm_source=luma), the second-hand market for camera and video equipment, running good ol' Django. Be sure to chat to them while you sample their food and drinks. This month, like last, we'll have a speaker from within our own community, **Sofia Fischer**, Backend Developer at Kraken Technologies. The title of her talk is: "**How complex is my function?**". This talk will give an overview of complexity metrics in computer science, software engineering, and linguistics to show many different ways in which a function may be complex. Based on the Django Framework repo, I will show how a project can be analysed with different complexity metrics. As always, please make use of the **lightning talks** and talk about anything you like: a problem that you'd like help with, a thing you've built, or a hobby you like. Doesn't have to be Django, doesn't even have to be tech! **18:30 Doors open** **19:00 Main talk by Sofia Fischer** **19:30 Lightning talks** **19:45 Get eatin'** This event is governed by the **[Berlin code of conduct](https://berlincodeofconduct.org/de/?utm_source=luma).** We want this to be a safe space for all. Any questions and concerns can always be directed towards the organizers Lara Krämer ([lara.softwareengineer@gmail.com](mailto:lara.softwareengineer@gmail.com)) and Markus Binsteiner ([markus@frkl.dev](mailto:markus@frkl.dev)) before, at and after the event. **Accessibility information:** The main entrance can be accessed via stairs or a ramp. The front door is a bit heavy and must be opened manually when closed. An elevator is available to take you up to the fifth floor. Once you reach the office door, please ring the bell; when you hear a sound, turn the handle two full turns to the right to enter, or somebody can come and open the door.
