Summary
🤩
RockstarSky Wilshaw is a PhD candidate (University of Nottingham) based in Cambridge with six years of software engineering experience researching the semantics of memory safety and borrowing. He blends formal methods research with hands-on theorem-prover engineering, contributing to the widely used mathlib4 by porting Lean 3 libraries to Lean 4 and resolving intricate type-inference and annotation issues. His work sits at the intersection of mathematical rigor and backend engineering, making proof assistants more practical for real-world mathematics. That combination gives him a rare ability to translate subtle type- and borrow-related theory into robust, maintainable code.
