I build secure, high-throughput .NET microservices and responsive web applications for enterprise platforms.

At Ride with GPS, I own architecture for route-planning and ride-navigation services, reducing route API latency by 32% and improving deployment reliability by 28%.

Previously at Dataminr, I built real-time alerting services that reduced incident-processing latency by 35%, alongside analyst-facing React applications, SQL Server data workflows, and enterprise identity integrations. At Zoot Enterprises, I developed financial decisioning services supporting secure loan, credit, and fraud workflows for banking clients.

I've spent 7+ years building production-grade systems with C#, .NET Core, React, cloud infrastructure, automated testing, and secure OAuth2/OIDC authentication. I also mentor engineers, lead architecture and code reviews, and investigate production issues across distributed systems.
