What I'm looking for

I seek a role focusing on backend Java development within an agile team, emphasizing scalable systems, performance optimization, mentoring opportunities, and strong testing and CI/CD practices.

I am an agile-minded Java developer with expertise in scalable application design, algorithms, and performance optimization. I have delivered full-stack and microservices-based applications using Java and Spring Boot, improved system modularity and deployment speed, and profiled and tuned applications to boost response times and query performance.

I have trained and mentored developers in Java Core and Spring Boot, authored course materials and documentation, and implemented security best practices such as JWT and SSO. My work emphasizes maintainable code, test automation, and collaborative practices that reduce defects and speed delivery.
