Meet us for in-person talks at Zalando on February 17, 2026! Join us for an evening of practical talks on how GenAI is reshaping modern engineering workflows, from code agents to production-grade, guardrailed systems. Please make sure you register with your full name, as it will be checked by security on arrival. **📅Date and Time:** Tuesday, February 17, 2026 Doors open: 18:00 Opening & announcements: 18:30 Talks start: 18:35 Wrap-up & networking: \~20:30 📍**Location:** [Zalando Office BHW](https://maps.app.goo.gl/GELYd8FH7AnqEFNF8) Berlin Hedwig-Wachenheimstraße 7 (BHW) The main entrance is on the west-side of the building (towards Uber Arena). Participants should register at the Helpdesk, and will be picked up from there. 📝 **Agenda:** **18:00 – Doors Open** Pizza, drinks, and networking **18:30 – Opening** Short welcome and announcements from the organizers (5 min) ### **18:35 – Talk #1** **Building Blocks of Modern Code Agents: Reusable Skills and Role-Based Subagents** **[Alexey Grigorev](https://www.linkedin.com/in/agrigorev) — DataTalk.Club** A practical map of modern code agent types and the two key building blocks that make them reliable in real-world development workflows. Code agents appear in many forms today: chat-based assistants, cloud agents running CI-like workflows, and IDE or terminal agents embedded directly into development environments. In this talk, we’ll map these main categories, discuss what each is good at, and highlight where they commonly fail. We’ll then zoom in on two core building blocks used in modern agent tooling: * **Skills / playbooks** — reusable, step-by-step workflows (e.g. understand the repo → implement a change → run checks → produce a clean diff) * **Subagents** — specialized roles such as planner, implementer, reviewer, and tester that split complex work into focused, reliable steps **Format:** 20 min talk + 10 min Q&A ### **19:05 – Talk #2** **Guardrailed Agents at Scale: Zalando’s Support Agent for Incident Triage and Stakeholder Q&A** **[Ivan Potapov](https://www.linkedin.com/in/ivan-sur/)**, **[Saugandh Karan](https://www.linkedin.com/in/saugandh-karan/)**[ ](https://www.linkedin.com/in/saugandh-karan/)— Zalando SE We’ll share how Zalando built and shipped a specialized internal support agent that helps engineering teams answer stakeholder questions and triage operational alerts — without drowning in context or compromising production safety. The agent enriches user requests with relevant observability context (metrics, logs, traces, recent deploys), summarizes what matters, and produces a severity assessment with recommended next steps. A key challenge is context explosion: pulling “all the data” quickly becomes noisy, slow, and risky. We’ll walk through the architecture patterns and guardrails that keep the system production-ready: * Retrieval and ranking strategies * Strict tool boundaries * Policy-driven response formats * Evaluation checks to prevent overconfident or unsafe guidance Finally, we’ll cover rollout and migration: introducing the agent alongside existing workflows, aligning it with architecture guidelines, and iterating based on real incident feedback. **Format:** 20 min talk + 10 min Q&A ### **19:35 – Pizza, Drinks & Networking** Invite your friends and join our meetup. Special thanks to our hosts **[Zalando.](https://en.zalando.de/?_rfl=de)**

**PyBerlin: February's event** **Sponsor**: **Sentry** **Location: W3.Hub** **Agenda:** 6:30 pm – Doors open: snacks, drinks, networking 6:55 pm - Welcome from PyBerlin 7:00 pm - Welcome from the sponsor - Sentry 7:10 pm – **Maximum time off, minimum leave: solving the holiday equation with Python and math // Sander Van Aken** Around the beginning of the year, German news sources publish tips on how to optimize your vacation by cleverly using Brückentage: taking a few strategic days of leave to connect weekends and public holidays into long breaks. But how can this be computed systematically? And how can it be tailored to your personal preferences? Operations Research (OR) and mathematical optimization are powerful but often underrepresented disciplines within the broader AI and analytics landscape. In this beginner-friendly talk, we treat holiday planning as a mathematical optimization problem. Using the question “How do I maximize my benefit from taking time off?”, we will walk through the full process from problem formulation to a working Python solution. Speaker's bio: Sander Van Aken is Operations Research Engineer and passionate about applying quantitative methods to solve mobility, logistics and supply chain planning challenges. Beyond his day-to-day job of developing decision support algorithms for network planning at Flix SE, he is active in the broader OR community and loves introducing people to the field. 7:40 pm - break 8:00 pm – **Exception Handling Within the Context of Python's Typing System // Jonathan Herrera** A conceptual approach to exception handling, with a special focus on Python's type hinting system. Python's typing system does not allow for annotating methods with the exceptions they raise. The talk discusses the conceptual consequences of this limitation and introduces different exception handling paradigms with their upsides and downsides. Speaker's bio: Jonathan has worked as a Senior Python Developer in different companies. Currently, he is an Engineering Manager at RoomPriceGenie, a scale-up providing revenue management solutions to hotels, where he oversees the integrations team, and works, amongst other things, on establishing best practices with regard to reliability and security. 8:30 pm – **One does not simply send a GET request // Paweł Wiszniewski** Short presentation on a few of the less-known features of the requests and urllib3 libraries. Regardless of whether you're scraping the web or extracting data from those REST API endpoints, you need a reliable and convenient way to download data from the internet. But packages get lost in the traffic, servers get overwhelmed with requests. And your job is to build a resilient data pipeline. Let's see what the most popular HTTP libraries have to offer. Speaker's bio: Paweł is a Senior Data Engineer and a founding member of the Data Platform team at Flink SE, where he builds tools and designs processes that empower data scientists, analysts, and business teams across the company. 9:10 pm - closing This event will be only in-person. Please check our Code of Conduct and official health regulation in Berlin before coming. If you feel some signs of sickness, please consider skipping this event and attending another time. We will have plenty of events in different formats in the future. Looking forward seeing you all!

**ℹ️ The next meetups will be managed on Luma.** **You can register for this event 👉 [here](https://luma.com/yx73udov). Follow the Django User Group Berlin Calendar on Luma.** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- ​This time, we'll be hosted again by **[Kraken](https://kraken.tech/)** (the clean tech company, not the crypto one) - one of the largest Django codebases and employers. Be sure to chat to them while you sample their food and drinks. Our speaker, **Johannes Tigges**, consultant in Open Collaboration, Community Management, OSPO, spatial technologies, and DevOps, will give the main talk on: **“21 Days: The Free Beer That Turned Into a €500K Bill — and what to do about It”** Covering SBOMs, licenses, and why FOSS isn’t always as simple as it seems. 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 Johannes Tigges** **19:30 Lightning talks** **19:45 Get eatin'** This event is governed by the **[Berlin code of conduct](https://berlincodeofconduct.org/de/).** 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) and Markus Binsteiner (markus@frkl.dev) before, at and after the event. **Accessibility information:** The main entrance door to the building is quite heavy and must be opened manually, as does the office door. There are a few steps leading to the elevator, along with a relatively steep ramp built into those stairs. If you need assistance, please reach out to us and we will do everything we can to accommodate you.

Save the date! The Mozilla Meetup series continues with talks focused on modern web technologies. To account for typical **no-show rates**, we’ve opened more RSVP spots than we can physically accommodate. Based on our last event, only about 36 of 100 registered participants (including Mozillians) attended in person. **We will admit attendees on a first-come, first-served basis and will need to close the doors once we reach room capacity (around 50 people).** Note that this event operates under the [Mozilla Community Participation Guidelines](https://www.mozilla.org/about/governance/policies/participation/). **18:00** \- Doors open **18:30** \- Tracking \(Protection\) Everywhere There are a variety of tracking vectors on the web. But how exactly does this tracking work and what mechanism do we have available to protect our privacy? This talk takes a closer look at the many anti-tracking mechanisms Firefox uses to protect its users, and discusses the threat models behind them and the practical protection they provide. Bio: Manuel Bucher is a software engineer on the Firefox Privacy team working on anti-tracking in Firefox **19:30:** No Servers, No APIs: AI in the Browser I’ll present how modern web technologies make it possible to run AI models directly in the browser combining WebLLM and WebAssembly to deliver powerful, privacy-preserving client-side AI experiences. For more context, here’s a related article I wrote for Mozilla AI: [https://blog.mozilla.ai/3w-for-in-browser-ai-webllm-wasm-webworkers/](https://blog.mozilla.ai/3w-for-in-browser-ai-webllm-wasm-webworkers/) **Bio:** Barış Güler is an engineering leader working on in-browser AI systems that leverage WebLLM, WASM, and web platform features to bring AI inference and tooling into client environments. He writes about web-native AI and open-source approaches to privacy-first machine intelligence (and a Rust fan, for sure).

**Rust Berlin on location 🏳️‍🌈** is a new, informal in-person Rust meetup group in Berlin. We are a interactive meetup format interested in mob coding, deep diving and problem solving together. We build toy projects, share experiences, discuss technology and learn new cool stuff. And you are welcome to join! No matter if you are writing Rust production code every day, if you already contribute to Open Source projects or want to start doing so, if you use Rust in hobby projects or if you are just curious what the hype and buzz is all about, you are very welcome! To coordinate and plan activities, please join our **[Rust Berlin on location 🏳️‍🌈](https://signal.group/#CjQKIApfEgb36v82nhIb7m6zLCQjEtSEZubR7UvywTcWZXxdEhBWxhMWNCKekvtCYX7iDRRm)**[ Signal group](https://signal.group/#CjQKIApfEgb36v82nhIb7m6zLCQjEtSEZubR7UvywTcWZXxdEhBWxhMWNCKekvtCYX7iDRRm)! **Planned programme** Being an informal meetup, we are open to anything between just meet and talk, explore nerd snipes and rabbit holes, mob code together, plan and build fun projects, tinker with electronics, and presentations with Q&A. This time, Flix will walk us through error handling approaches in Rust — from typed error enums to crates like anyhow and thiserror — and present his own take: neuer-error, a single-type error library that captures source locations instead of backtraces and provides typed, discoverable error context without generics soup. Then Raf will show off a fun project that renders canvas primitives with vector and matrix geometry, built from scratch with zero dependencies. If someone brings other cool stuff, questions or problems, then let us dedicate the second half of the meetup time to that! Anyone is invited to bring their projects and questions, show something, ask something, or explore a topic together. The best conversations and deepest rabbit holes can emerge out of seemingly nowhere. **Projected upcoming meetups** We schedule regular meetups on Thursday evening every four weeks, using the slot between the Berlin Rust Hack and Learn online meetup (every two weeks), and the Rust Nuremberg online meetup (every four weeks). 19 February 2026 is our eleventh meeting. Our next projected meetings are going to occur on the following dates: * 19 Feb 2026 * 19 Mar 2026 * 16 Apr 2026 * 14 May 2026 (tentative, public holiday) * 11 Jun 2026 * 9 Jul 2026 * 6 Aug 2026 **Location** Our meetup location is the new shared office community space of Ferrous Systems, Slint and KDAB in Berlin Mitte, for up to 25 people. We are expecting to use this space as our default location for the time being, with the IN-Berlin e.V. community space in Moabit as backup. Regardless, as our group might eventually outgrow the locations' size limit, we are low-key looking for bigger locations. If you know a fitting location, then please let us know in our Signal group! Another workable way might be to split the meetup into smaller, interest-specific sub-groups instead. As the no-show rate on Meetup.com is rather high, consider showing up even if you are on the waiting list. We can't promise that there is any space left, but usually there is. So give it a shot! **Accessibility** The location has an elevator and a wheelchair accessible bathroom. Please note that the bathroom is two floors down from the meetup space. On our quest for a bigger location, we are going to pay special attention to accessibility. **Community** We aim to create a safe place for everyone and adhere to the [Berlin Code of Conduct](https://berlincodeofconduct.org/). Inclusivity is very important to us. If you are curious about Rust, but unsure if you are welcome to join: Yes, yes you are. Please come to the meetup! If you have special needs, please get in contact, we will try to accommodate you as best we can. We are part of [https://berline.rs/](https://berline.rs/) and like to hang out in the Berlin Rust Hack and Learn online meetup's [Matrix channel](https://matrix.to/#/!xycQxSjSAvEezkyztA:chat.berline.rs). You are very welcome to join!

Bring your work or your hobby, hang out, and code with us. Follow @buckeyecocoa for more information.
