With 25+ years building mission-critical trading systems for investment banks, hedge funds, and professional traders, I bring genuine front-office experience to every project - not just technical skills, but a deep understanding of what traders actually need and the low margin for error that comes with it. My background includes roles on the trading floors of ING Barings and UBS Securities, where I developed equity solutions in high-pressure, time-critical environments. Since then I've worked extensively with hedge funds and private investors, most recently in an ongoing relationship with a New York hedge fund spanning 5+ years, building strategy screeners, broker connectivity via Interactive Brokers/QuickFIX, and risk management reporting across Excel, Python, and Azure SQL Database. One of my core specialties is the intersection of Excel and C# - building sophisticated, real-time trading tools using Excel DNA, multithreaded C# DLLs, and custom broker APIs that go well beyond what standard VBA can deliver. I'm equally comfortable at the quant/data layer (Python, Plotly Dash, Bloomberg, Eikon) and the execution layer (QuickFIX, FIX Protocol, broker APIs). I have a particular talent for untangling complex, hard-to-reproduce bugs in live trading environments - the kind of problems that require both deep technical knowledge and genuine market understanding to diagnose. I'm looking for long-term client relationships with serious projects. If you're building something sophisticated in the trading/fintech space, let's talk.
