Summary
🤩
Rockstar🎓
Top SchoolJad Ghalayini is a Quantitative Developer and CS PhD student at Cambridge with seven years of experience bridging rigorous theory and high-performance software. His work sits at the intersection of formal methods, refinement types, and compiler design, aiming to create zero-cost abstractions that improve safety and efficiency in real-world systems. At TypeFoundry he contributed research on refinement types and intermediate representations before joining Xantium Group / Tudor Investment Corporation to apply those skills in quantitative software. Trained at Oxford and Toronto, Jad combines deep mathematical intuition with practical systems engineering, from proof-oriented research to production-grade optimization. He’s equally comfortable proving properties about programs and squeezing out low-level performance, making him a rare practitioner who turns formal guarantees into fast, usable tooling.
