Golang Developer
Software Engineer
Backend engineer, 6+ years building production systems in Golang. Most of my work involves concurrency, distributed archi-tectures, and microservices. At my current role I tracked down a Kafka bug that was silently corrupting transactions across 140M+ monthly messages. I also contribute to Zed Editor in Rust (24 PRs, including a macOS deadlock fix and new debugger features) and build Web3 projects in Solidity and Rust.
