Software engineer with 6+ years building resilient, high-performance systems for financial and Bitcoin applications. I focus on reproducible infrastructure, secure backend systems, and developer-centric tooling, primarily in Rust, TypeScript, Nix, Terraform, and Kubernetes.

Currently building bitcoin-collateralized banking infrastructure using event-sourced architecture and domain-driven design. Previously the principal maintainer of a bitcoin wallet that shipped to 150K+ users on iOS and Android, where I owned UI/UX revamps, CI/CD automation, and staggered rollouts.

Earlier, I contributed to the Bitcoin Dev Kit as a Summer of Bitcoin 2021 intern, working on Miniscript, Descriptors, and PSBTs.

Distributed systems, event sourcing, zero-knowledge applications, Bitcoin and Lightning, Rust ergonomics, and reproducible infrastructure with Nix.
