About

Senior Backend Engineer with 4.5 years of experience designing and building scalable distributed systems using Java, Spring Boot, and Microservices architecture. I’m passionate about solving complex engineering challenges and creating reliable backend systems that scale seamlessly. At Cars24, I led the design and development of the Car Health Report platform, capable of generating 50+ page reports in under a minute by orchestrating data from multiple microservices in parallel — a product now driving ₹12Cr+ in annual revenue. I also built the Order Management System processing 10K+ daily orders, powering payments, refunds, and fulfilments across business workflows. Previously at Airtel IQ (India’s largest CPaaS platform), I developed and optimized microservices managing 10M+ intelligent phone connections. My work on Spring WebFlux re-architecture improved system performance by 40%, and I co-owned an inventory management system maintaining 400M+ mobile number records. I enjoy working on system design, performance optimization, and distributed data processing, and I’m always eager to collaborate on backend systems that push the limits of scalability and reliability.
