I am very product focused with my projects. I have Claude write 100% of the code but I challenge its suggestions and make damn sure there are ways for it to verify functionality and correctness. I don't read much of the generated code but am adamant that there are tests: unit, integration and (if possible) against other implementations. And I care a LOT about performance.

So far (last 6-7 months) I've built tons of stuff in my spare time: A pdf generator lib, a scheme implementation (R5RS and R7RS) with AOT compilation, a screenplay editor, a code editor, a ripgrep-like lib/engine/cli tool for fast search in a workspace, a markdown parser, a Fountain (screenplay) parser, a lib for dealing with updating apps, tooling for finding duplicate code and generating codemaps - and much more.

It's been an absolute ride.
