About

As a Software Developer at Jio Financial Services, I specialize in backend development for JioFinance and the MyJio App, contributing to high-scale fintech solutions that cater to millions of users. My expertise lies in designing and optimizing microservices-based architectures that enhance performance, security, and scalability. In my role, I have built and optimized prepaid recharge functionalities, designed secure authentication mechanisms using Spring Cloud Gateway and JWT, and developed high-traffic bill payment systems handling transactions worth millions of rupees. My work also includes integrating Jio Finance UPI and Jio Payments Bank into payment flows, ensuring seamless digital transactions. With a strong foundation in Java (Java 8–17), Spring Boot, and microservices, I leverage technologies like Redis, OracleDB, MySQL, Docker, and Kubernetes to create robust and efficient backend solutions. My experience also extends to frontend development with React.js, enabling me to build full-stack applications when needed. Previously, as a Software Engineering Intern at Samsung SDS, I developed core frontend components, improving cross-device compatibility and enhancing user engagement. I am passionate about solving complex engineering challenges, driving innovation, and continuously improving fintech applications to provide seamless and secure financial experiences for users.
