Software Engineer
Software engineer focused on Bitcoin, Rust, and backend systems. My path into Bitcoin grew from production backend and security-sensitive infrastructure work into full-time open-source contribution: I have contributed 20+ patches and reviews across the rust-bitcoin ecosystem through Vinteum, landed merged work in Bitcoin Core, corepc, rust-bech32, and rust-bitcoin, and worked on wallet-privacy tooling, RPC schema metadata, and Bitcoin infrastructure. Previously, I worked on Coinbase’s identity team, maintaining authentication systems used by millions of users and fixing a login timing side channel. My background also includes Go, Python, C/C++, Linux, AWS, Terraform, Docker, Kubernetes, PostgreSQL, distributed systems, DevOps, testing, and security-focused backend engineering. I am especially interested in Bitcoin protocol, ecosystem infrastructure, embedded systems, privacy. Open to backend/platform roles.
