The wild journey from Domain Specialist to Domain Developer that understands the complexities of the technology that powers the fixed income markets and uses agentic coding to build practical solutions.

With over 20 years of global experience in the fixed income sector, I bring a deep commitment to finance, having collaborated with industry leaders in London, New York, San Francisco, and Dallas. My career has been driven by a passion for the digitization and electrification of bond markets—transitioning from using the tools to architecting them.

My career began at Bloomberg LP, implementing and promoting the Trade Order Management System (TOMS) for regional broker-dealers and banks. This provided the foundational understanding of how technology optimizes trading operations and market efficiency.

In 2010, I transitioned to Vice President roles at Dallas-based broker-dealers, overseeing electronic trading systems. I developed innovative trading strategies and platform capabilities that delivered significant revenue growth while deepening my knowledge of algorithmic and platform-based trading solutions.

As European Client Relationship Manager at Algomi Ltd in London, I specialized in tailored trading solutions, including the deployment of ALFA (liquidity aggregation) to tier-1 asset managers.

In 2019, I founded CatFIX Technology, Inc., a cloud-native FIX protocol engine aimed at modernizing fixed income marketing for regional banks—leveraging technology to address evolving market demands and improve operational workflows.

From 2020 to 2021, I launched a revolutionary machine learning platform that analyzed 200 million bond pairs with 91% accuracy. Originally an ING spin-out, Katana became my mission. I crafted its go-to-market strategy, secured its Google Cloud Partner Advantage status, and drove its integration onto the Bloomberg Terminal (reaching 325,000+ users).

The Acquisition: When liquidation loomed, I submitted an initial £9,000 bid to review the financials. To my surprise, I secured the IP for £25,000.

The first Google Cloud invoice, nearly matching my bid, marked a turning point. It prompted me to pause everything and dedicate myself to mastering cloud management to preserve Katana’s potential.
