About

Ownership over the hard parts.

Backend engineer at Amdocs. Five years in Java and Spring Boot, owning services within a large-scale microservice platform.

I care about the parts of backend work that are hard to get right: throughput, reliability, and clean delivery. I re-architected a data-intensive processing flow using pagination, asynchronous calls, and Kafka, cutting API times ~40% and regression runs ~50%, then packaged the logic into a shared library reused across multiple services.

Production and delivery aren’t separate roles for me: I own services end-to-end — design through CI/CD to production support — and keep systems healthy under real load.

Selected work

Projects that show how I think in systems.

Earlier engineering work, reframed around concurrency, domain modeling, and full-stack delivery — the same instincts I bring to backend services today.
