Engineering Leader · New York City
I like buildingthings that move.
Engineering leader in New York City — writing software since 2008. Currently on Goldman Sachs’ Private Wealth platform; previously Peloton’s e-commerce replatform, institutional bond trading at ICE, and HFT systems that filled arbitrage in 26 milliseconds. I lead teams, mentor engineers, and ship with AI.
Arbitrage systems under 26ms. Real-time volatility across 40+ exchanges. Infrastructure where milliseconds change outcomes.
Portfolio systems at Goldman. Interfaces that brokers and high-net-worth clients rely on. Precision, governance, responsibility.
Operational platforms for coworking and physical space. Software that touches real-world infrastructure.
NextJS, React, LangChain, GPT-4. Tools that compress iteration cycles. Product built fast, but built right.
- Built reusable Control Bar + Currency Picker — adopted across the broader app
- Led portfolio UX redesign + frontend refactor; aligned with internal design system
- Lifted unit-test coverage to 80%+ with Jest, strengthening release reliability
- Mentor + onboard analysts on architecture, testing, and code quality
26 zero-dependency TypeScript libraries — Treasury and rates math, market-data clients, FX conventions, volatility models, Hebrew NLP — each verified against primary sources and maintained on GitHub.
I’m interested in leverage — the kind you get from code that moves capital, systems that scale without drama, and teams that outlast their founders.
Eighteen years in, the pattern is consistent: I join where the stakes are measured in milliseconds or millions, build the thing, raise the people, and leave the platform stronger than the slide deck said it would be. Lately that means putting AI to work inside real products — not demos.
