What I'm looking for

I seek senior full‑stack roles where I can design scalable microservices, modernize stacks, mentor teams, and deliver secure, production-grade systems using cloud and CI/CD practices.

I am a Senior Java Full Stack Developer with 8+ years of experience building scalable enterprise applications across Banking, Finance, E‑Commerce, Telecom, and Healthcare domains.

I design and implement Spring Boot microservices (Java 8–17), migrate frameworks and build automation, and optimize backend systems using PostgreSQL, Oracle, and MongoDB for high throughput and reliability.

On the front end, I deliver responsive React and Angular applications using Hooks, Redux/NgRx, PrimeReact/Material‑UI, and real‑time UI patterns, integrating seamlessly with RESTful APIs and event streams like Kafka.

I champion secure, production‑grade solutions—implementing OAuth2/JWT, PCI‑DSS/HIPAA controls, containerized deployments with Docker/Kubernetes on AWS, CI/CD automation, and mentoring teams to improve code quality and developer productivity.
