Senior Software Engineer at DraftKings who cut live-game wagering API p95 latency from 400ms to 120ms.

At DraftKings, I architect high-traffic sports betting and contest APIs with C# and .NET Core, cutting p95 latency from 400ms to 120ms during peak live-game wagering. I also engineer real-time odds processing services on AWS and use Kafka to connect distributed services.

At Uber, I developed ride-hailing marketplace microservices and reduced deployment build time from 12 minutes to 4 minutes. Earlier at Spin, I built backend rental APIs and fleet operations tools for dockless micromobility systems.
