A living library of production-proven reference architectures, decision records, and engineering principles for growing teams.
How a team running 80+ microservices adopted spec-driven development without a framework: six core ideas, an AI-native meta-repo where agents see the whole system at once, and a triage step that keeps most work away from specifications altogether.
Why standard CI/CD pipelines are vulnerable to zero-alert credential exfiltration, where preventive controls reach their limit, and how to design build systems that contain compromise and win on time.
Building Azek, a personal AI agent that runs entirely on hardware I own. What it actually takes: the constraints that justify building instead of renting, and the architecture decisions that keep a single-GPU host fast, private, and cheap.
Geo-sharding looks trivial to adopt — add a shard key, keep data close to users. That simplicity is exactly where the expensive failures hide. A field story about symptoms, root cause, and the bill that arrives monthly.
One authorization model, three deployment shapes. Where in-process guards stop being enough, what an externalized PDP really costs once you measure it, and how to go node-local without trading away data freshness or latency.
