About

I build and run the platforms that investment teams depend on - and I have sat on the other side of them as a portfolio manager. I started in operations, became a market maker, then joined Millennium Partners as Head Trader and built the firm's original trading desk - execution infrastructure, operating workflows, and trade-lifecycle controls - at the start of a run that took the platform from $1.5B to $8.6B in AUM. I then co-created and ran a statistical arbitrage (quantitative equity long/short) strategy at $900M per side for seven years. From there I moved to the platform side of the same relationship. At Lehman Brothers I rebuilt the RealTick electronic execution platform for institutional hedge fund workflows. At Momentum Trading Partners I ran trading operations and technology firmwide. I was later invited back to Millennium as an outside consultant to design and build an internal trading application for its investment teams. Most recently I have led global platform organizations at Bank of America, Enfusion, and Linedata - spanning PMS, OMS, and EMS architecture, risk and valuation systems, execution infrastructure, and the front-office technology interface across equities,
