About

As a software engineer with focus on system design and scalability, I’ve developed key services to boost user engagement. Designed payment systems including support for cards , autopay and upi which handles around 90k+ transaction daily. Leading team of 4 members which designed and developed backend systems for an android application. In addition, I contributed to the Babelfish Extension (Open Source), allowing PostgreSQL to interpret SQL Server commands. I optimized frequently used Transact-SQL functions, cutting runtime by 30%, and enabled seamless database object migration, reducing migration time by 40%. I have also successfully handled the migration tasks of major merchants like Jio Saavn, Udaan, and Cars24, upgrading their UI to the latest versions while addressing critical issues for Times Prime’s payment checkout. My work has streamlined payment instruments, leading to a 40-50% improvement in efficiency.
