About

I’m a Software Development Engineer with experience building scalable backend systems in fintech and enterprise platforms. Currently at Zeta, I work on post-issuance systems for HDFC Pixel Credit Card serving 5L+ active users, where I’ve contributed to critical features like UPI-based autopay and launch-ready card configurations. Previously at Tekion, I led the end-to-end development of the Syndication feature, enabling dealerships to seamlessly publish vehicles to ad agencies through customizable rule-based workflows. I also optimized system performance by migrating Drools rule engines to Java functions, reducing memory usage by over 80%. I enjoy designing high-performance distributed systems using Java, Spring Boot, Kafka, Redis, and scalable data stores. Strong problem-solving drives my engineering approach — I’ve achieved ICPC regional ranks and maintain strong competitive programming profiles across Codeforces, CodeChef, and LeetCode. I’m passionate about building reliable backend systems, improving performance at scale, and solving complex engineering problems.
