- Accomplishment
Shipped the async job runner behind a feature flag. Cut p95 checkout latency from 840ms to 210ms.
- Learning
Studied Postgres LISTEN/NOTIFY — cleaner than polling for what we needed, but doesn't survive reconnects.
- Improvement
Getting faster at reading unfamiliar codebases. Started at the tests, not the entrypoint.
- Worked on
Draft RFC for splitting the monolith's billing module. Two more sections to go.
