Robust systems aren't built by adding resilience at the end. They start with strong fundamentals, thoughtful tradeoffs, and an understanding of how software behaves when assumptions fail. I use this site to explore those ideas, from algorithms and software construction to distributed systems, microservices, performance, and reliability. I also write about lessons learned while building real systems: what worked, what didn't, and how I'd approach the problem differently today. The goal isn't to have all the answers. It's to become a better engineer by examining the decisions behind the systems we build.
