What I'm looking for

I’m looking for a role where I can build secure, maintainable Java microservices and responsive front-ends, own RESTful APIs, and improve reliability with CI/CD and monitoring in Agile/Scrum teams.

I’m a Java Full Stack Developer with over 4 years of experience building lifecycle projects using Java and J2EE. I focus on scalable back-end services and microservices with Spring Boot, Spring MVC, Spring Security, Spring Data, and Spring Cloud, while staying strong in core Java fundamentals like OOPS, Collections, multi-threading, and exception handling.

I build end-to-end solutions with React.js/Redux and Angular 8, designing responsive, secure user experiences and RESTful APIs. I’ve implemented CI/CD with Jenkins and Docker, deployed microservices on OpenShift, and supported production reliability through monitoring tools like ELK Stack, Prometheus, and Grafana—always delivering maintainable, high-performance systems.
