What I bring

My work sits at the intersection of backend architecture, distributed processing, production reliability, and technical leadership. I build systems that handle scale, review design tradeoffs carefully, and raise engineering quality through mentorship, code reviews, and operational ownership.

Designing distributed systems and microservice platforms with Java and Spring Boot.
Owning backend architecture decisions for large-scale production services.
Leading incident response, root-cause analysis, and reliability improvements.
Mentoring engineers and improving engineering quality through reviews and delivery discipline.

Professional journey

I have worked across mapping, healthcare, banking, finance, and publishing. The common thread is backend ownership under real constraints, scale, and reliability pressure.
