10+ Years Building Enterprise Systems
Explore My WorkProfessional Summary
Senior Full Stack Developer with 10+ years of experience designing and delivering complex enterprise systems across biometrics, telecom, identity management, and SaaS platforms. Proven track record in microservices architecture, cloud infrastructure (AWS, Kubernetes), and secure authentication systems (Keycloak, mTLS). Deep expertise in Java SpringBoot, React/Next.js, Angular, and multi-database strategies (PostgreSQL, Couchbase, Elasticsearch, MongoDB).
I am particularly drawn to environments where engineering rigour meets product impact — where the systems built have real consequences for the people and organisations that rely on them. I thrive in collaborative, technically ambitious teams and am equally comfortable leading architecture decisions as I am writing production code.
