Fix bugs and flaky tests in existing codebasesSebastian Lim
Cover image for Fix bugs and flaky tests in existing codebases
I help teams fix bugs, flaky tests, and edge-case failures inside existing codebases.
My best work is small, reviewable patches that improve reliability fast — especially in Go and TypeScript repositories where the goal is not a rewrite, but a targeted fix that maintainers can review and merge quickly.
What I can help with:
flaky CI failures
race conditions and timing bugs
missing awaits and async test issues
brittle assertions in test suites
framework and validation edge cases
What you get:
root-cause analysis
a small, reviewable fix
regression test updates when needed
clear implementation notes for handoff or PR review
Good fit if you already have:
a live codebase
a reproducible bug or flaky failure
a team that wants the smallest safe fix
