What to expect?
Mikołaj Roszczyk - Multi-Agent AI System in JavaScript? Sure, let’s try!
I’ve read Sam Bhagwat’s “Principles of Building AI Agents” so you don’t have to. The book is based on author’s own agentic framework Mastra.AI. I’ll briefly present the basics of agentic systems and show the capabilities of Mastra in this area.
Mateusz Żeromski - AI Agents Live: Building Your Ideas from Scratch
Forget slides and scripts. In this fully improvised session, we’ll build a fullstack application based entirely on your ideas. Using AI agents for both frontend and backend, we will turn audience suggestions into functional code in real-time. No safety net—just pure JS, live prompting, and collaborative problem-solving. Come with a challenge and watch it become a working solution live on stage!
Krzysztof Rzymkowski - Using Text as UI. Why Your Next Form Should Be a Code Editor
Clicking through fifty dropdown menus to configure a resource is tedious and error-prone. There is a better way. By treating user input as a Domain Specific Language (DSL), we can offer an interface that is faster, flexible, and far more powerful. Join this talk to see why Text is the ultimate UI.
