A Modern App Development Meetup

Agents can write your UI now. The more interesting question is what that does to everything around the writing - the design handoff, the review, the verification, the call on what actually ships. JetBrains, Callstack and Expo are teaming up for an evening in Amsterdam on exactly that. Three talks, practical and production-level. Whether you build for web, mobile or both, if agents are already in your workflow (or about to be), this one's for you. ─── AGENDA ─── 17:45 · Doors open 18:10 · Intro & welcome 18:20 · From Design to Done in One Shot With a Cheap Model 18:45 · Talk 2 (TBA) 19:10 · Agents Didn't Kill the UI Developer Workflow – They Changed It 19:35 · Networking, pizza & drinks ─── TALKS ─── From Design to Done in One Shot With a Cheap Model by Michał Pierzchała · Principal Engineer, Callstack Getting a frontier model to one-shot a mobile design into a working app is simple enough, and usually works ok-ish. But what if you don't have access to one and still want to turn designs into shipped features, repeatedly and at cost? Michał walks through the simple verification loops that take the chance of a PR getting merged first go from 60% to 98%. Agents Didn't Kill the UI Developer Workflow – They Changed It by Craig Walker · Product Manager, JetBrains (WebStorm), and Kasper Peulen · Software Engineer, Chromatic (StoryBook) As AI agents take over the mechanical work of writing UI code, developers are spending less time in design, code, and verification and more time between them — composing intent, steering output, and deciding what ships. A look at how Storybook's new agent-native CLI and WebStorm's design-to-browser agent workflows are each built for exactly that shift. Cedric van Putten · Expo Abstract coming shortly. ─── GETTING IN ──── We're hosted at the JetBrains Amsterdam main office. It's a secured building, so there are two check-in steps: Check in at the ground-floor reception and give your name. A JetBrains team member will be there to welcome you. Head up to the 6th floor and complete registration at the JetBrains reception desk. You'll be pointed to the meetup space from there. Please register in advance and use the same name you'll give at reception — building security can't let in anyone who isn't on the list. Bring ID, and give yourself a few minutes for check-in. Free to attend. Pizza and drinks after the talks.
