Four things, done properly, rather than a list of everything I could theoretically take on. If what you need is not here, say so anyway — I would rather point you somewhere good than take work I would do badly.
A site designed and built end to end — not a template filled in. Content-driven, so you can change it without me.
Putting a model into something that has to keep working — retrieval, tool use, evaluation, and the unglamorous parts around them.
Database through interface. Schema design, API, auth, admin tooling, and the front end that sits on top of it.
Interface design that survives contact with a real codebase, because it was drawn by someone who will also build it.
