Welcome to our next community MeetUp! The pace of change in software delivery isn’t slowing down—and neither are we. For our upcoming MeetUp, we’re once again bringing together Berlin’s engineers, architects, and tech leaders to explore the move from classic automation to Agentic AI and intelligent cloud workflows. 18:00 - Welcome & Networking 18:30 - Short Introduction & First Talk 19:15 - Break with food & drinks 19:45 - Second Talk 20:30 - More Networking & cold drinks Here's a quick intro to our speakers and what they'll be talking about: **Speaker:** Alberto Miorin and Valery Lavrentiev – Staff engineers (https://www.linkedin.com/in/albertomiorin/ and https://www.linkedin.com/in/valery-lavrentiev-5467782/) **Talk:** BigConfig: The First Agentic Package Manager In this talk, Alberto and Valery introduce BigConfig, an open‑source Clojure/Babashka infrastructure package manager built for agentic workflows. The session shows why higher-level, composable packages are needed instead of raw Terraform, Ansible, Helm, or YAML. It also demonstrates how natural-language plans are turned into auditable bb.edn configurations and deployable infrastructure packages. Alberto is a Berlin-based engineer with a background in DevOps, Data, and AI. He previously helped scale the data platforms at Zalando and OneFootball. Valery Lavrentiev is a Berlin-based AI/ML engineer who played a key role in building the OneFootball personalization engine. **Speaker:** Saeid Mirzaeiaraghi - Senior Software Engineer at Cluster Reply (https://www.linkedin.com/in/saeid-mirzaei/) **Title:** Agentic Documentation with GitHub Copilot Learn how GitHub Copilot transforms codebases into living documentation using AI-driven workflows for architecture, APIs, and onboarding.

Two talks. One evening. Plenty of ideas to take home. We’re ready to kick things off for another Berlin Meetup, and are happy to present the speakers of the evening: **[Jens Wriske](https://www.linkedin.com/in/jens-wriske-8b538a397/):** ***"Designing APIs on top of Data Platforms using Databricks"*** Modern data platforms increasingly follow a lakehouse architecture, where data remains owned and governed by domain teams rather than application developers. This session explores how APIs can be designed on top of Azure Databricks to provide access to heterogeneous data sources without duplicating or owning the underlying storage layer. **[Tanuj Jain](https://www.linkedin.com/in/tanuj-jain-10/): *"The Story Behind the Story: "Building a Contextual News Chatbot."*** Most news readers lack the background to fully engage with the stories they encounter. This talk walks through the development of a chatbot embedded in a news article page for a German news publisher, designed to give readers on-demand context about what they're reading. We share the key technical and product decisions made along the way, and what we learned about building an AI feature that sits at the intersection of editorial and user experience. ✧ ✧ ✧ **What to expect:** * Two expert talks and Q&A * Networking opportunities in our great Creator Space * Some snacks & drinks to fuel your thoughts : ) ✧ ✧ ✧ **Timetable:** * 18:30 - Event admission * 18:50 - Welcome & Introduction * 19:00 - Jens Wriske: *"Designing APIs on top of Data Platforms using Databricks"* * 19:30 - 5 minutes break * 19:35 - Tanuj Jain: *"The Story Behind the Story: Building a Contextual News Chatbot"* * 20:05 - Snacks, Drinks & Networking * 21:30 - End ✧ ✧ ✧ More on the **-> [applydata data engineering meetup page](https://applydata.io/data-engineering-meetup/)**. **Our goal is to form a local data-loving community, so join us and let's talk data together!** ✧ ✧ ✧ *At the event, sound, image and video recordings are created and published for documentation purposes as well as for the presentation of the event in publicly accessible media, on websites and blogs and for presentation on social media.

Bring your laptop! ​The session will last around 2 hours, followed by a networking session with dida and fellow AI enthusiasts (and free pizza!🍕). Bring your laptop! **​Abstract:** Nearly every cancer diagnosis still begins with a pathologist examining a stained tissue slide under a microscope. Digital pathology turns those slides into gigapixel images — and with them, a uniquely demanding frontier for machine learning. But getting from raw pixels to clinically meaningful, quantitative insight about a tumor and its microenvironment is far from trivial. ​In this workshop, Aignostics — a computational pathology company and Charité spin-off — walks you along the arc from core ML research to real-world application. We start with an overview of digital pathology and what makes it challenging for ML (gigapixel images, scarce labels, scanner and staining variability). We then look at how pathology foundation models are built and what separates a good one from a fragile one — not just accuracy, but robustness to non-biological artifacts — with a short hands-on segment. Finally, we put these models to work: with Atlas H&E-TME we profile the tumor microenvironment from routine H&E slides, and you'll get hands-on with OpenTME — an open dataset of TME profiles across five cancer types from TCGA — and TME Studio to run your own analyses. **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend.

Wir stoßen dies durch eine moderierte Kontaktrunde an, in der sich jeder Teilnehmer kurz vorstellen (ca. 1 Minute) und anschließend intensiven Austausch mit den anderen Teilnehmern betreiben kann. Bringt bitte nach Möglichkeiten **Visitenkarten** mit, da diese uns das Netzwerken erleichtern. Zu Beginn der Veranstaltung gibt es einen kurzen Impulsvortrag; Thema diesmal: Wie du als Unternehmer in die Sichtbarkeit mit Reels kommst. In einem kurzen Impuls gibt Moderator Oliver Gehrmann ein paar Einblicke in die Möglichkeiten, dem eigenen Business mit Hilfe von Kurzvideos ("Reels") auf Plattformen, wie YouTube, Instagram und TikTok zu mehr Sichtbarkeit zu verhelfen. Wir gehen auf Fragen ein, welches Equipment benötigt wird, worüber man als Unternehmer am besten spricht und welchen Effekt man sich letzten Endes wirklich davon erhoffen kann. \-\-\- Solltest du ebenfalls Interesse haben, einen Impulsvortrag zu halten, so schreib uns sehr gerne. Weitere Informationen gibt es auch hier: [Impulsvorträge bei BNB](https://netzwerken.berlin/impulsvortraege/) \-\-\- Alle Gründer/StartUps, Freiberufler und Unternehmer/Unternehmensvertreter sind willkommen beim Business MeetUp im Café Amelie im Prenzlauer Berg.

Weiterhin stehen wir auch allen Arten des Provisionsgeschäfts (Finanz-Optimierer, Immobilienmakler, Versicherungsvertreteter, etc.) extrem kritisch gegenüber und gestatten diesen keine Teilnahme an unseren Events. Solltet ihr der Meinung sein, ihr fallt nicht in diese Kategorie, obwohl ihr in einer der genannten Branchen arbeitet, so sprecht uns bitte im Vorfeld an. Für alle anderen Fragen zum Event stehen wir euch selbstverständlich ebenfalls zur Verfügung. Wir freuen uns darauf, auch dich persönlich kennenzulernen und dir bei der Entwicklung deines Geschäfts zu helfen! P.S.: Es werden mitunter Bilder auf den Events gemacht.
