What I'm looking for

I’m looking to lead Java microservices and full-stack delivery in Agile teams—architecting secure cloud-native systems (AWS/Azure), strengthening CI/CD with quality gates, and mentoring engineers while shipping measurable business impact.

I’m a Principal Software Engineer with 9+ years of experience designing, developing, and deploying scalable enterprise applications across banking, healthcare, and SaaS domains. I focus on Core/Advanced Java and Spring Boot microservices, with a strong track record delivering production-grade systems in Agile teams.

I architect scalable microservices and build REST APIs, using Spring Boot, OAuth2/JWT authentication, and RBAC authorization to secure enterprise workflows. I also optimize performance with JPA/Hibernate ORM and tuned HQL/SQL for high-volume processing.

I lead development teams end-to-end—driving code reviews, mentoring junior developers, and enforcing clean-code and design patterns (OOAD, DDD, CQRS via Axon IQ where needed). I embed continuous quality into delivery by integrating CI/CD pipelines with Jenkins and Docker and adding SonarQube quality gates.

On the product side, I deliver responsive UIs using Angular/AngularJS (and React in some engagements), and I’ve supported cloud-native, multi-tenant healthcare platforms with strong security practices (encryption and audit logging). My goal is always reliable delivery, measurable quality, and maintainable architectures that scale.
