Hi! My name is Jack and I'm a developer/writer.

End-to-end, open & open. Until every end-to-end flow is open to public.

Fullstack developer focused on AI-powered web apps, LLM systems, and open-source tools.

Small projects from time to time, most big projects are in orgs!

I like useful software, silly ideas that somehow work, and small projects that teach lessons.
