What I'm looking for

I'm looking for global B2B consulting, contract, or remote roles where I can accelerate OMS/EMS implementation, trading connectivity, client onboarding, integration, product, or market-infrastructure roadmaps.

I've led electronic trading connectivity and OMS/EMS delivery for Fidessa and SunGard Financial Systems, supporting global buy-side and sell-side clients across Europe, the US, and Asia.

At Fidessa, I managed buy-side FIX Connectivity Services Operations for Minerva LatentZero OMS clients connecting to brokers and liquidity pools across equities, futures, fixed income, and FX. I introduced onboarding procedures and tools that helped double connectivity revenue in 2009 and 2010.

Across GL TRADE and SunGard, I built and managed FIX and OMS teams, led professional services delivery, coordinated API and exchange-connectivity projects, and provided product and pre-sales consultancy. I've delivered implementations for tier-one financial institutions and worked with order routing, DMA/NDMA, UAT, software releases, and market infrastructure.

I'm now focused on independent, remote-ready trading technology consulting, combining FIX and capital-markets experience with Python automation, data analytics, digital assets, AI, and Model Context Protocol applications.
