    What I Do

    Java Backend Engineer with 4 years of experience building enterprise applications, REST APIs, workflow automation platforms and scalable backend systems using Java, Spring Boot and relational and NoSQL databases.

    Over the past 4+ years I've worked on enterprise platforms for government and private sector clients — from e-File workflow systems and HRMS platforms to developer automation tooling. I care about clean APIs, reliable deployments, and backend systems that hold up under real-world load.
