I am a Java Backend Engineer specializing in scalable enterprise applications, microservices architecture, and clean code methodologies. I turn complex logic into performant APIs.

About & Skills

I am a Java Backend Engineer with 3 years of professional experience developing enterprise-grade systems. I specialize in building resilient, high-availability services on the JVM, with a strong focus on clean architecture and domain-driven design.
