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)**

This is an [in-person communication lab](https://www.presentation-school.com/berlin-presentation-lab) that helps professionals speak clearly and confidently under pressure using proven methods. Most people don’t struggle because they don’t practice enough. They struggle because they practice without the right principles. This session focuses on deliberate, guided practice informed by performance psychology, neuroscience, and modern communication training. **What You Will Do** * Learn one science-based communication principle that improves real-world performance. * Train that principle in structured speaking exercises designed for skill development. * Receive clear, professional feedback you can apply immediately. Practice and feedback are guided by experienced communication professionals who work with executives and senior professionals. This is not peer-to-peer feedback or open discussion. **Who Should Attend?** * Non-native English speakers * Professionals who present, lead meetings, or speak up at work * Anyone who overthinks, freezes, or loses clarity under pressure * People who want structured improvement, not just repetition No prior experience is required. **What This is NOT** * A lecture. * A motivational talk. * A public performance. * Unstructured open practice. * Peer-led feedback or opinion-based critique. **Before The Session** Before the session, participants complete a short preparation form to clarify their goals and common communication challenges. This helps ensure the practice and feedback during the lab are as relevant and effective as possible. **Optional:** Participants may submit a short video (1–2 minutes) or written questions. This is optional and used to personalise focus areas and examples during the session. No individual coaching is provided. **After the Session** Participants receive a short follow-up pack with key takeaways, practical drills, a reflection question, and guidance on next steps. **Practical Information** Language: English Duration: 2 hours Format: In-person, structured group lab Address: Chausseestraße 86, 10115 Berlin Healthy snacks and water provided. Price: €25 per session If you are looking for a professional, practical way to improve how you communicate and want to train using principles that actually lead to results, this lab is a good place to start.

In this Yin practice, we take time to pause, soften, and simply be. With the support of long-held, floor-based postures, the body gradually opens, accessing the deeper layers of fascia and energy pathways. We allow gravity to guide the process. This subtle work calms the nervous system, nurtures stillness, and encourages quiet reflection. It's an opportunity to release tension from both body and mind, and to reconnect with yourself on a deeper level. The class is led in English and is open to all levels. .
