Rockstar🎓
Top SchoolOliver Flatt is a PhD student in Computer Science at the University of Washington with 11 years of engineering and research experience focused on compilers, theorem proving, and automated reasoning. He contributes to high-performance open-source tooling—most notably enhancing explanation generation, proof production, and performance in the e-graph library egg—demonstrating deep systems-level insight into proof-producing infrastructures. His work sits at the intersection of formal methods and practical engineering, including a formally verified authorization optimization for Amazon’s Cedar (proved in Lean). Past roles span automated solver development for numerical stability, full-stack internships, and building testing frameworks for synthetic biology tools, showing adaptability across domains. Based in Salt Lake City, he combines rigorous formal verification skills with hands-on performance optimization and a knack for turning complex proofs into efficient, production-ready implementations.
