Rockstar🎓
Top SchoolBolton Bailey is a consultant and proof engineer with 11 years of experience blending formal mathematics and systems engineering, currently based in Palo Alto. He holds a BS in Mathematics and Computer Science from Caltech and completed graduate work at UIUC, where he honed formal-reasoning and proof engineering skills. Bolton has contributed to prominent open-source projects—refactoring Lean 3's mathlib and documenting core components of RISC Zero's zk-STARK-based platform—demonstrating both theorem-proving fluency and practical cryptographic systems knowledge. He focuses on backend correctness and clear documentation, often surfacing subtle bugs and improving lemma reuse and core-proof plumbing. Colleagues describe him succinctly as a "proof dude" who turns formal ideas into maintainable code and crisp developer-facing documentation.
