What I'm looking for

I'm looking to lead sportsbook trading, pricing, risk, and operational strategy in a high-volume environment where data-driven decisions, market responsiveness, system integrity, and team development are valued.

I've led trading and risk management at Bettors Den and 5Dimes, compiling and adjusting odds across pre-match, live in-play, props, and futures markets for U.S. and global sports.

Across more than two decades with 5Dimes, I've managed exposure, customer profiling, sharp and syndicate action, competitor analysis, and real-time pricing while collaborating with technology teams on data feeds, trading systems, and sportsbook improvements.
