Rewrote the hot path in TypeScript. p99 latency dropped noticeably. Read the flamegraph before touching anything. #webdev
Wrote docs for the migration runner that I'd actually want to read. If the README lies, the code isn't done.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Migrated file uploads from Axum to Svelte. Boring, reversible, no downtime. Exactly how I like it.
Rewrote the hot path in Ruby. bundle size dropped noticeably. Read the flamegraph before touching anything.
Spent an embarrassing 3 hours chasing a bug. Root cause: an N+1 query. Fix was three lines. The classics never miss. #rustlang
Migrated the media encoder with zero downtime via expand/contract: add nullable, dual-write, backfill in batches, switch reads, drop old. 6 deploys instead of one scary big-bang. Boring migrations don't page anyone.
TIL: SQLite handles way more concurrency than I assumed. How did I not know this.
Migrated the job queue from React to Svelte. Boring, reversible, no downtime. Exactly how I like it.
Rewrote the hot path in Ruby. Allocations way down. Read the flamegraph before touching anything. #databases
