About

I'm Lei Wang, a builder and entrepreneur with over a decade of experience designing and operating scalable, production systems.

My work spans financial systems, distributed systems, and infrastructure, with a strong emphasis on correctness, reliability, and long-term maintainability. I've built and run real-world platforms across startups and enterprise environments, staying hands-on in both software development and operations.

My engineering approach favors simple, explicit designs and functional programming principles to reduce complexity and make systems easier to reason about. I spend a lot of time in the practical layers—Go and Clojure codebases, databases, Kubernetes clusters, and CI/CD pipelines—where abstractions are tested by reality.

Lately, I've been focused on making systems more AI-native, experimenting with AI agents and modern tooling in ways that complement, rather than replace, solid engineering fundamentals.

I write here to think in public: sharing ideas, lessons learned, and ongoing experiments from building and operating systems.
