Talks abstracts
Sharpen the axe first: think before you vibe
The real work happens before you open the chat. I'll share my approach - why I invest time upfront on a PRD, design system, and starting prompt before jumping into prompting. I'll walk you through Squeeze, a native macOS app built with Codex that solves a real daily problem at our agency.

Codex at scale - hands on, buidling an Open Source ERP (Open Mercato)
Piotr will show what works for them in building an Open Source ERP with 40+ contributors. What changed, what not, and what the software engineering looks like at the AI edge. Features presented: custom skills, Task Router / AGENTS.MD, Playwright integration testing framework; techniques: spec-driven development, code review on steroids, and feasibility studies.
Piotr Karwatka, Co-Founder @ Open Mercato + Catch the Tornado / OSS founder & contributor
