Join us for the Callstack x Vercel AI SDK Meetup in Wrocław - a hands-on, developer-first event hosted by Callstack and sponsored by Vercel through their Meetup SDK program.

This event dives into how AI is transforming modern app development across web and mobile. Explore the transition from AI prototypes to production by mastering secure code execution, durable agentic architectures, and "vibe-coding" fully functional commerce storefronts. Learn to leverage the Vercel AI SDK, Workflows, and Claude to build reliable, long-running systems that ship with the speed and scale of the modern web.

Whether you're a full-stack developer, senior engineer, app architect, or exploring cross-platform AI solutions, you'll gain actionable knowledge from industry experts pushing the boundaries of intelligent applications.

It's the perfect spot to network with fellow pros, exchange ideas, and get fired up about building smarter, faster AI-powered software. The agenda is pure fire so we hope to see you in Wrocław!

Talks and speakers

The safe detonation chamber: Building AI you can actually ship

You’re building a SaaS where LLMs write and run code. It feels like magic… right up until things start timing out, vendors get sticky, and security becomes “uh oh.”

In this talk, we’ll walk through how to build a kind of safe detonation chamber for AI - a setup that lets you experiment fast without blowing up production.

Using the modern Vercel stack, we’ll look at how Sandbox keeps risky code contained, Workflows lets long-running jobs finish instead of die halfway through, and the AI SDK helps you stay flexible instead of locked into one model.

Szymon Chmal: Creator of Rozenite, Harness and Voltra. The kind of person who dives into code and somehow makes the "impossible" happen. Focused on building the next generation of developer tools so you can ship your apps even faster.

Building modern Lovable for commerce with Vercel and Claude

Most “AI website builders” vibe-code pretty pages that break the moment you need real commerce.

Your Next Store (YNS) lets you vibe-code an actual store. You prompt our AI Builder (backed by Claude) to build and iterate on a live storefront that’s already wired to a real commerce backend via the Commerce SDK – products, cart, checkout, the whole thing.

Every prompt updates a running store on Vercel, so you can launch in minutes and keep shipping changes at the speed of thought.

Jakub “Zaiste” Neander: CEO and co-founder of Your Next Store (YNS)

Michał Miszczyszyn:  CTO and co-founder of Your Next Store (YNS)

You can just ship Agents: Architecting for the Agentic era

Enterprises are moving fast from AI prototypes to production-ready agent systems. Solutions architect Dom Sipowicz explores how modern teams are building reliable, long-running, and observable agents without reinventing orchestration.

Using the Vercel AI Cloud and the new Workflow Development Kit, Dom shows you how durability, retries, and human-in-the-loop approvals become first-class features of your architecture. Learn how these patterns make it possible to design, prototype, and scale agents with the same ease as any modern web application.

Dom Sipowicz: A Solutions Architect on Vercel’s Professional Services team, where he helps global enterprises adopt AI workflows and implement production-grade agents using the Vercel AI Cloud. With over 15 years in web architecture, he’s led billion-pound commerce replatforms and built high-performance Next.js applications focused on scalability and Web Performance. Dom frequently speaks at conferences and meetups on Next.js, AI and modern web architecture.

About Callstack x Vercel AI SDK Meetups

Callstack has been investing in AI, exploring how it transforms the way we build software. Together with Vercel, sponsoring the event as part of their Meetup SDK program, we’re hosting a community meetup in Wrocław to share what we’ve been working on and where the field is heading.

You’ll hear about running LLMs on-device in React Native and what’s new in Vercel’s AI SDK and it’s ecosystem. ‍Expect practical insights, live demos, and perspectives from teams already applying AI in production.
