I design and build scalable distributed systems, working across Java, Spring Boot, React, Angular and Kubernetes — from architecture to production.

About

Engineer by trade, builder by instinct.

I design and ship microservices, own features end-to-end, and care deeply about code quality, test automation, and developer experience. Lately I've been deep in cloud-native fraud-prevention infrastructure — distributed systems, OpenSearch, and Kubernetes — while leveraging AI-assisted tooling to move faster.

Outside of work: photography, guitar, ice skating, running, and the occasional tennis match.
