What I Have Delivered

Exchange Connectivity

90+ Global Venues

Eight years at IMC Financial Markets building and maintaining connectivity across CME, Eurex, ICE, NYSE, OPRA, and 85+ additional venues. FIX protocol, proprietary binary protocols, session management, failover. The infrastructure that keeps a top-three global options market maker trading at the latency markets demand.

Goldman Sachs Reconciliation System

630+ Securities. Four Months. Inception to Production.

Designed and delivered the centralized reconciliation system when IMC acquired Goldman Sachs’ NYSE DMM rights for 630+ securities. The constraint was real: the desk was live, the positions needed reconciling daily, and there was no existing system to inherit. Built from inception to production in four months.

ETF Trading Desk

Full Stack Launch. Zero to Live in Three Months.

Built the real-time ETF basket valuation system that launched IMC’s ETF trading desk. Real-time NAV calculation, basket composition tracking, arbitrage signal generation. Zero to live trading in three months.

Apple Music Classical

The Database Apple Acquired

Built the metadata database at Primephonic that Apple acquired in 2021 and relaunched as Apple Music Classical. The engineering challenge was classical music’s unique taxonomy: a single composition can have thousands of recordings from different artists, orchestras, conductors, and eras. The database modeled that complexity at scale. Read: Parsing the Da Capo Catalog →

Healthcare Technology

2 US Patents — Emergency Radiology Workflow

Two granted US patents covering emergency radiology workflow systems: closed-loop critical study notification and escalation chain systems. Both in production use. The patents demonstrate the breadth of production engineering across domains — and support O-1A extraordinary ability visa pathways for US engagements.
