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.

Meetups and workshops

Friendly, hands-on sessions for exploring Codex across the App, CLI, IDE, and Cloud.

Events and hackathons

Collaborative build sessions where developers turn ideas into useful prototypes and share what they learn.

Reusable learning resources

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

Build with the community
