About

I am a backend developer currently working as an Associate Java Developer at Perennial Systems since May 2022, with over 4 years of experience in software development. My background includes a Masters of Computer Applications from SRM Institute of Science & Technology and a Bachelors of Computer Applications from University of Petroleum & Energy Studies. My work spans Java, Spring Boot, Apache Kafka, Redis, Docker, Kubernetes, and Maven, where I have built and optimized microservices, improved API latency, and implemented caching and event-driven systems. I have also integrated CI/CD pipelines, enhanced monitoring with Grafana, and maintained high test coverage using JUnit and Mockito, contributing to production readiness and team mentoring.

What I'm looking for

I'm looking for a backend software engineering role where I can build scalable products with real user impact. I enjoy working with Java, Spring Boot, microservices, Kafka, and cloud technologies on distributed systems and APIs. I value ownership, strong engineering practices, and collaborative teams. I'm excited by opportunities to learn, solve challenging problems, and contribute to products used at scale.
