I work on TypeScript and React codebases where the hard part is interaction: pointer handling on Canvas, focus and keyboard behavior, and packaging boundaries. Most of what I send upstream is small on purpose — a reproducible failure, the narrowest fix for it, and regression coverage that explains why the fix is there.

- Small, reviewable changes with a stated reason. If I cannot say why a diff exists, it does not go out.
- Reproduce first, cover the reproduction, then widen scope — not the other way round.
- Answers go on the review thread that raised the question.
- Project conventions and scope boundaries are part of the implementation, not overhead.
- I cap external work at three concurrent PRs and one open PR per upstream repository, unless a maintainer asks for a split.
