Resiliency • Real-Time • AWS

Building fault-tolerant, low-latency systems that keep traffic flowing.

Principal Software Engineer focused on enterprise-grade resiliency engines (Go, ECS/Fargate, Route 53, CloudWatch, DynamoDB, New Relic). I design systems that detect failure quickly and route around it— at scale.

About

I'm a systems-minded engineer with a sports background and a love for building real-world systems that withstand failure. I lead the design & evolution of a Go-based resiliency engine that monitors multi-region AWS deployments and dynamically routes traffic to healthy resources.
