I’m a Java Backend Developer with 4+ years of experience building scalable, high-performance systems. I focus on object-oriented design, clean APIs, and database performance to deliver reliable features for internal and partner use.

In my current role at Infosys, I’ve developed and maintained Java/Spring Boot web applications and implemented PL/SQL stored procedures and views that improved database performance by 40%. I also built RESTful APIs and published them to the WSO2 API manager for consumption across teams.

I strongly value production excellence: I troubleshoot complex issues with root-cause solutions, reducing client-reported incidents by 25%. I also automate CI/CD pipelines using GitHub actions, cutting deployment time by 50%, and support continuous delivery through Agile ceremonies.

I enjoy collaborating across cross-functional teams and mentoring others—I've mentored three junior developers through code reviews and pair programming to improve code quality and sprint velocity. I’m especially motivated by real-time, event-driven architectures, cloud deployments, and systems that can evolve safely in production.
