Own feature development end-to-end: scoping, building, shipping, iterating.
Maintain and extend existing codebases with a focus on quality and speed.
Use AI coding tools ( Claude Code, Codex, or equivalent) as your primary development workflow — the expectation is that you multiply your own output through these tools.
Flag gaps or ambiguity in requirements before they become problems — write lightweight specs when needed.
Read and interpret product metrics to understand how features are actually performing.
