Join us for an in-person 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 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:** **17:30 – Doors Open** Arrivals and check-in \*\*\* **18:00 – Talk #1** **Research Harness Engineering** [Florian Hönicke](https://www.linkedin.com/in/florian-h%C3%B6nicke-b902b6aa/) — Elastic Every programmer is now a manager of coding agents — but human oversight quickly becomes the bottleneck. Florian will share how Elasticsearch 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 – Talk #2** **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 – Talk #3** **Ranking Logic Migration from Monolith — Using Code Agents for Iterative Performance Benchmarking** [Ivan Potapov](https://www.linkedin.com/in/ivan-sur/) — 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 \*\*\* **19:00 – Talk #4** **Coding Agents for ML Pipelines & AI Systems (Hopsworks + Claude Code)** [Jim Dowling](https://www.linkedin.com/in/jim-dowling-206a98/) — 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** \*\*Host: Ivan Potapov Jim Dowling — CEO, Hopsworks Leela Sharma — Director of Engineering, Zalando Alexey Grigorev — Founder, DataTalks.Club Florian Hönicke — Principal AI Engineer, Elastic 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! **⚡️ Interested in giving a talk? ⚡️** Are you interested presenting on your Elastic use case?

Making open models reliable at scale Dylan Bristot, Product Marketing, Token Factory Sujee Maniyam, DevRel, Token Factory  ### 14:30-15:00 –– Coffee break  ### 15:00-15:25 –– Breakout sessions: select your preferred track on the registration form **Track 1 — Partner talk: Anyscale** Physical AI at scale: Efficient VLA training on hundreds of GPUs Carl Winkler, Anyscale Physical AI is entering a new era, with VLA models reshaping how robots learn to see, reason, and act from a single architecture. But scaling VLA training across hundreds of GPUs exposes a core infrastructure challenge: the data is heterogeneous, the compute is heterogeneous, and in traditional batch pipelines, expensive GPUs sit idle while CPU steps run. This talk shows how streaming execution eliminates that waste by continuously feeding data through CPU and GPU stages in a single unified pipeline, keeping GPU utilization near 95% instead of waiting for each step to complete. We will walk through the full data pipeline, from show how fault-tolerant streaming on Anyscale, deployed on Nebius AI Cloud, lets teams efficiently utilize hundreds of GPUs, process massive multimodal datasets, recover from failures without restarting from scratch, and dramatically speed up the development cycle from data to training. **Track 2 — Workshop** Hands-on with OpenClaw: Bring your own model Mikhail Rozkhov, TPM, Nebius In this hands-on workshop, you will learn how to deploy a custom model and connect it to OpenClaw to build a usable AI service. We start by deploying a model to a serverless endpoint, making sure it is accessible, stable, and ready for inference. From there, we integrate the deployed model with OpenClaw, configuring it to handle requests, route inputs, and expose a clean API. Along the way, we cover the practical details that matter in real setups: model compatibility, endpoint configuration, and how to make the system reliable end to end. By the end of the session, you will have a working pipeline where your own model is deployed, connected to OpenClaw, and ready to be used in real applications.  ### 15:25-15:50 **Track 1 — Agentic Search: Context Management in Research Agents** Agentic search is not just about retrieving information. It is about delivering the right context, in the right form, at the right time for an agent to reason effectively. In this talk, we explore the architecture behind deep research systems through lessons from building Tavily’s research API. We examine how agent harnesses are designed, how context is managed across multi-step workflows, and which context engineering techniques most improve performance in practice. Evan Rimer, Forward Deployed Engineer, Tavily **Track 2 — Workshop** Hands-On with OpenClaw: Bring Your Own Model (continued) Mikhail Rozkhov, TPM, Nebius  ### 15:50-16:05 –– Keynote address  ### 16:05-16:20 –– Fireside chat with keynote speaker Waqas Makhdum, VP of Developer Relations & Community, Nebius  ### 16:20-16:30 –– Wrap up and closing remarks Waqas Makhdum, VP of Developer Relations & Community, Nebius  ### 16:30 –– Help bar Networking happy hour with bites

The topic for May is "Ink" Speak Easy: true stories, told live. The idea is simple: an audience, an open microphone, and great stories. Hilarious, gripping, poignant- it's up to you. Audiences are invited to come to listen or come to tell as folks from all corners of Columbus offer their stories live on stage! Held at Wild Goose Creative's warm, intimate space, this night of tales occurs on the 3rd Thursday of every month. Doors open at 6:30 pm, show starts at 7:00 pm. Please arrive early if you want to tell, as we generally only have room for a limited number of tellers, and the sign-up sheet has a tendency to fill up fast. Formed around the idea that people need stories--they're what hold and draw us together--SpeakEasy celebrates the strangeness and commonness of being human. And in a world of smartphones, Facebook, Twitter, and more . . . it gives people a real, breathing, in-person way to connect. The night is geared for true stories of all kinds, taking the best tales told around kitchen tables, in darkened pubs, on the street corner, and at late-night parties and giving them an audience. Speak Easy is also a great outlet for performers, writers, and artists looking to share their favorite stories and perfect their skills. We strongly encourage tellers to please tell the story rather than read it so we keep within the spirit of good storytelling and stay engaged with the audience. All are welcome. Hang around after the show for a drink and build community!

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
