A remote build cache: 22-minute CI down to 4

2024 · Tech lead

The remote build cache that took our monorepo from a 22-minute median pipeline to 4 minutes, on the GitHub Actions runners we already had.

Median PR pipeline 22 min → 4 min. Cache hit rate 71% sustained. ~$18k/mo of CI compute reclaimed.
Quill: a tiny config-loader 2.4k people now use

2023 · Author and maintainer

A 4kb TypeScript library for typed config from env vars and JSON/YAML overlays, with a test mode that catches missing keys at build time. MIT.

2.4k weekly downloads. 38 contributors. Used in production at three companies I know of and probably more I do not.
Cutting p95 latency 40% by moving auth to the edge

2022 · Senior engineer, infrastructure

Session validation and per-request authorization moved to a Cloudflare Worker in front of the origin. Same contract, far less application work.

Authenticated p95 latency 312ms → 187ms. p99 cut by 38%. Origin egress dropped 22% as a side effect.
