About

As a Backend Developer at Refyne India, I work with a team of engineers to build scalable and reliable solutions for the gig economy. We design and implement APIs, microservices, and integrations that enable real-time payments and financial wellness for workers. Some of the projects I have contributed to include creating a notification service, enhancing the authentication and authorization system, and optimizing the database performance and security. I have a Bachelor of Technology degree in Computer Science from Indian Institute of Information Technology, SriCity, where I gained a strong foundation in data structures, algorithms, and software engineering. I also have an IBM Industry Project Certification, which demonstrates my ability to apply industry best practices and standards to a real-world problem. I have been working as a Backend Developer for over a year, starting as an intern at Refyne India and Volopay, where I learned and applied various technologies, frameworks, and methodologies, such as NestJS, Node.js, MongoDB, Agile, and DevOps. I am passionate about creating innovative and impactful solutions that improve the lives of millions of people in the gig economy. I am always eager to learn new skills and technologies that can help me grow as a professional and as a person.
