Open to Software Engineering roles
Building fast, reliable systems with Java, Spring Boot, Angular, AWS & modern web.
Seattle-based Full Stack Engineer specializing in scalable backend systems and cloud-native architectures. I design production-grade microservices, optimize PostgreSQL for performance at scale, and build Angular applications that stay fast under real-world load.

Microservices + events
What I’m good at
- Building Spring Boot microservices end-to-end
- PostgreSQL performance: indexes, plans, schema
- Angular modular UI + lazy loading
- Kafka async flows with idempotency + retries
About
Engineering approach
I keep architecture simple, enforce API contracts, measure performance, and ship in small safe increments. If it can’t be observed in logs/metrics, it doesn’t exist.
