​Bring a project. Build with Codex.

​A hands-on evening for people using Codex to build real software.

​We’ll open with a few short, practical demos, then spend most of the night building. Bring a product, work repo, side project, or rough idea and use the time to move it forward.

​New to Codex? You’re welcome. Come for the walkthroughs, then build alongside people already using it.

​Codex is OpenAI’s coding agent: https://developers.openai.com/codex

​Format

• ​5:30pm: Doors open

• ​6:00pm: Welcome, followed by two short talks:

  • ​Long-running Cloud Agents: The Harness and Infrastructure
    Harry Nguyen

  • ​Building Platform: Rapid mobile app development
    Immanuel Lam and Hunter Balderson

  • ​Each talk will open a track you can use as a starting point, or you can continue working on your own project.

• ​6:30pm: Supported coworking. We’ll be around to help you get unstuck, make introductions or find someone to pair with.

• ​8:00pm: Optional five-minute community share-outs based on tracks

• ​8:30pm: Closing

​What to bring

• ​Your laptop and charger

• ​Something you’d like to build or improve

• ​A GitHub repo or starter notes if you have them

​No polished idea is required. You can pair up, ask for help, or work quietly.
