What I'm looking for

I'm looking to build reliable, real-time products where I can own architecture, improve performance and observability, and partner closely with product and domain experts to ship meaningful user-facing features.

I've built real-time, high-throughput products at DraftKings, including Sportsbook bet placement, live betting, same-game parlays, odds ingestion, and pricing pipelines that held up through peak NFL traffic. I use Node.js, TypeScript, React.js, Kafka, Redis, PostgreSQL, AWS, and event-driven services to make wagering experiences faster, more reliable, and easier to operate.

Before DraftKings, I delivered patient-monitoring software for Philips IntelliVue and ground-control, telemetry, and multi-vehicle autonomy software at Autonodyne. I enjoy working closely with product, risk, trading, clinical, and systems teams, while improving observability, automated testing, incident response, and the engineering practices that help teams ship dependable features.
