Senior🎓
Top SchoolJon Hanson is an Executive Director and seasoned software architect with 12+ years (and a career stretching back to the 1990s) building distributed, multi-tier risk and P&L systems for top-tier banks. He combines deep functional-programming expertise (Haskell, F#, Scala) with long-standing proficiency in Java/C++ and low-level languages, enabling pragmatic designs for real-time and end-of-day risk engines across rates, credit and equity derivatives. At Nomura he leads the Unity Data Warehouse and has previously headed global risk engine and limits platforms, delivering scalable front-office and stress-testing capabilities. His background as a quant developer and systems lead at Lehman, Goldman and Credit Suisse gives him rare cross-domain fluency in analytics, pricing and production engineering. Off the beaten path, his GitHub interests range from 6502/680x0 assembly and retro Basics to modern functional languages, reflecting a blend of systems-level curiosity and practical finance-grade software craftsmanship.
