About

I specialize in turning complex distributed systems into platforms that engineering teams can actually ship on. Most of my career has been spent at the intersection of architecture and execution — designing event-driven pipelines, decomposing monoliths into microservices, and building the CI/CD and observability tooling that keeps everything running.

At Ten Mile Square I lead the platform modernization of a core banking application, working across GraphQL, Kubernetes, and AWS. Before that I directed engineering at QL2 for a large-scale web data extraction system, built procurement intelligence infrastructure at TealBook, and led investment platform architecture at SigFig.

What I focus on

Platform & infrastructure design
Distributed systems & event-driven architecture
Cloud cost optimization (AWS, GCP)
Engineering team leadership (15+ people)

Currently

Consulting at Ten Mile Square on a banking modernization project — cloud-first, GraphQL, Kubernetes on AWS. Building PitchTrack on the side, an Apple Watch app for baseball pitch tracking written in Swift. Always tinkering with ML tooling on Kaggle.
