Personalisation Without the Price Tag - Local LLMs for JavaScript Developers
Workshop
Jo Franchetti
Jo Franchetti
LLMs are powerful but unpredictable and most tutorials skip the part where you actually have to deal with that in production code. This workshop teaches you to use generative AI as an engineering tool: how to structure prompts around schemas, validate and repair non-deterministic output, and run models locally so you control the cost and the carbon.

We'll generate a world for a roleplaying game as our teaching context it's a fun, low-stakes domain that makes the hard problems visible. The patterns you leave with apply anywhere you want to bring LLMs into a typed system.

No ML background required. Just TypeScript and a laptop.

Stress Test Your Reflexes (And My App)
What happens when you turn your audience into a live, distributed load test?We will kick off this session with a high-stakes, multiplayer "Whack-a-Mole" challenge played right from your phone. As you compete for the leaderboard, a live stream of concurrent data will be generated to showcase realtime web capabilities in action across devices.After playing around, it is time to get serious by digging into the challenges, architecture and technologies used when building such a platform. Discover how helpful or distracting AI can be during this process.Key takeaways include:AI: The Good & The Glitchy!The Stack: NextJS, Supabase.Realtime: No longer refreshing the page.Leave the theory behind and see how modern tools and a bit of trial and error handle the chaos of live user interaction.
