Current engagements confidential by agreement.
Track record
2023 – 2025 · Head of Technology
Built a fully redundant cloud-native footprint from zero — SQL Server, .NET and Python serverless, Power Automate, Power BI, BARRA risk integration, and custom biotech risk modeling — with DDQ-grade security posture.

Worked directly with Soros over four years on the bespoke portfolio management software he used personally — during a fifteen-year tenure at Soros Fund Management.

Based on the SAC trading floor. Built the firm's flagship real-time portfolio management application — iterated to Cohen's specifications, deployed across PM, operations, and execution desks.

Developed and supported the benchmark index platform used by over 100 financial institutions, plus the corporate bond pricing server feeding JPMorgan index systems.

Coding agents directed by a senior architect deliver production systems at a fraction of the cost and timeline of a traditional team.
The AI-native edge
The economics of software delivery have changed. A consultant with 30 years of production judgment, directing Claude-based coding agents, now ships institutional systems at a fraction of the cost and timeline of a traditional multi-person team.
No junior-engineer churn. No meaningful handoff cost. No ramp-up billed to the client. Every line of code passes through an engineer who has shipped production systems to the most demanding principals on the buy side.
Engage
Senior buy-side engineering, scaled by AI coding agents. One engineer, one relationship — discovery through delivery.
