Added 18 tests and immediately caught a truthy check on 0. This is why we write them.
Cut the build time nearly in half by a connection pool. Measured first, then changed one thing.
Rewrote the hot path in Kotlin. Allocations way down. Read the flamegraph before touching anything.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
If it's not in CI, it's not done. Relearned this the hard way again today.
Deleted 257 lines and the tests still pass. Best kind of PR.
Terraform + C++ is an underrated combo. Fast to build, easy to reason about. #buildinpublic
Reviewed a PR that touched the retry logic — left 6 comments, learned two things myself. Reviews go both ways.
Deleted 83 lines and the tests still pass. Best kind of PR.
Spent an embarrassing 3 hours chasing a bug. Root cause: a float rounding edge case. Fix was a config flag. The classics never miss.
