Reviewed a PR that touched file uploads — left 7 comments, learned two things myself. Reviews go both ways.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Small PRs get reviewed; big PRs get rubber-stamped. Relearned this the hard way again today. #opensource
Spent most of the afternoon chasing a bug. Root cause: an off-by-one in the cursor. Fix was a null check. The classics never miss. #perf
Kubernetes + Elixir is an underrated combo. Fast to build, easy to reason about.
Rewrote the hot path in Python. Allocations way down. Read the flamegraph before touching anything.
The bug is almost always in the last place you changed. Relearned this the hard way again today.
Rewrote the hot path in C++. Allocations way down. Read the flamegraph before touching anything.
Rewrote the hot path in Python. The GC pressure basically vanished. Read the flamegraph before touching anything.
Migrated the caching layer from Svelte to Rails. Boring, reversible, no downtime. Exactly how I like it.
