I've been a generalist for the last five years — making infrastructure work, building developer productivity tools, shipping end-to-end deployment and codeship pipelines for 250+ engineers, designing streaming ingestion systems on Kafka and Flink, standing up banking transaction engines, tinkering with AI agents, and writing frontend interfaces with optimistic updates and gesture-driven navigation. Along the way, I kept running into the same question: how does this actually work under the hood?
This site is where I answer that question. Each chapter takes something I've built in production and explains the fundamentals behind it — how parsers turn text into trees, how optimistic updates make interfaces feel instant, how timezone bugs creep into every calendar view. Real systems, real code, illustrated with diagrams.
