🔐 Cryptography & Systems Engineer | PDF Resume

I am a privacy-oriented software engineer with a strong foundation in applied cryptography, reliable data systems, and secure system design. I spent three years as a PhD researcher, exploring privacy-preserving computation, zero-knowledge proof systems, and consensus protocols, before transitioning full-time into engineering roles focused on cryptographic infrastructure.

At Unisys, I worked on OS-level TLS 1.3 implementation, internal certificate authority infrastructure, and CI/CD pipeline hardening. I’m fluent in Rust, C/C++, and Go, and passionate about building secure-by-design systems—especially in domains like encrypted search, vector databases, and secure ML pipelines.

I’m now focused on applying my cryptography and systems skills to problems in modern data infrastructure: secure query engines, privacy-preserving analytics, and next-gen databases for AI workloads.

💡 Always happy to connect with other engineers, researchers, or founders working at the intersection of privacy, performance, and systems innovation.

Outside of arguing with computers, I like to spend time visiting national parks. I love watching basketball and soccer, and playing pickleball and tennis. I enjoy reading sci-fi, fantasy, biographies, Mormon and CHamoru history, as well as the latest cryptography research papers.

I’m easily nerd-sniped and have an unhealthy addiction to finding answers to unimportant questions.
