Ambassador work

Bringing practical Codex learning to the community

My goal is to help people move from curiosity to working software through approachable learning, real workflows, and opportunities to build together.

Free community meetups

Meet people with similar interests, share ideas, and try Codex across the App, CLI, IDE, and Cloud.

Building together

Hands-on workshops and build challenges within our free meetups, with time to show projects and share what we learn.

Reusable learning resources

Articles, videos, demos, and workflows that make advanced Codex features easier to apply.

Build with the community

Upcoming Codex events

All my Codex events are free community meetups where like-minded people share ideas and learn together. These are community-led events, not official OpenAI events.
