We’re hosting Wrocław’s first official OpenAI Codex Community Meetup.

Join us for an evening dedicated to Codex, OpenAI’s coding agent that helps you build and ship faster.

The meetup will bring together developers who are curious about coding agents as well as those already experimenting with them in practice.

The focus is on sharing updates, real experiences, and open discussion around how AI is influencing modern software development. You’ll hear from OpenAI team & experts already using Codex in their daily work and connect with peers from the tech community.

### ​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.
