About

As a Backend Engineer at Jio Platforms Limited (JPL), I design and implement features for our AB Testing tool, RBAC system, and User MicroService, using technologies such as Java, Spring Boot, JPA, REST, GCS, Message Queue, and JWT. I work with a team of talented engineers and follow the Test Driven Development (TDD) approach to ensure the quality and reliability of our code. I graduated with a Bachelor's degree in Computer Engineering from J.C. Bose University of Science and Technology, YMCA, in 2022. During my studies, I completed several internships and projects, where I gained hands-on experience in web development, microservices architecture, data structures, algorithms, and various frameworks and tools. I am passionate about learning new technologies and solving complex problems. I am also fluent in English, Hindi, and Punjabi.
