Platform engineering is the discipline of building the foundations other engineers build on. Done well, it accelerates every team in the organization. Done poorly, it becomes the bottleneck nobody talks about until it breaks at 3am.

I’ve built platform infrastructure across multiple companies — from startup-scale single-cloud setups to enterprise multi-account, multi-region architectures. The posts here cover the practical decisions, hard lessons, and repeatable patterns I’ve encountered along the way.
