Jon Freedman is a Director and seasoned technology leader with over 15 years building scalable, AI-driven systems for hedge funds and asset managers, now providing fractional CTO services to buy-side firms. He has repeatedly transformed trading, risk and middle-office operations—scaling teams from single digits to enterprise levels and replacing Excel workflows with cloud-native, microservices architectures. Jon combines hands-on software craftsmanship (contributions to notable open-source projects like QuickFIX/J and js-joda) with strategic execution, turning technology into a P&L driver rather than a cost centre. His strengths lie in pragmatic automation, operational resilience and embedding AI where it reduces complexity, not adds it. Based in the UK with an MEng in Computing from Imperial College London, he pairs quant trading domain depth with a track record of measurable cost and efficiency gains. An interesting quirk: he’s comfortable authoring and fixing failing tests in core open-source FIX and time libraries, reflecting a developer-first approach to mission-critical finance systems.
