Opinionated conventions for reproducible developer environments and CI with Nix flakes.
Reviews PostgreSQL and MySQL schema migrations (raw SQL or ORM-generated) for table locks, rewrites, data loss, and breaking changes, then proposes safe zero-downtime rewrites with a clear verdict.
Reviews and rewrites Git commit messages to Conventional Commits quality — clear type/scope, imperative subject, useful body explaining why — and trains the author with concrete before/after feedback.
Compares environment variables across local, staging and production, finds missing, unused or mismatched settings before they break a deploy, and keeps your example env file honest.
Finds out why your CI builds are slow: tracks job times over weeks, spots missing caches, serial steps and oversized runners, and suggests concrete changes ranked by minutes saved.
Runs focused validation: tests, smoke checks, and acceptance criteria against a builder's patch.
Writes and runs tests for a teammate's change, reports failures with minimal repro steps, and asks for fixes.
