What I'm looking for

I’m looking for a backend role where I can build scalable microservices and performance-focused APIs, work with event-driven architectures (Kafka), and design reliable distributed workflows. I value engineering ownership, clean system design, and measurable impact.

I’m a Senior Software Development Engineer with 5+ years of experience building scalable microservices and high-performance APIs using Java and Spring Boot. I focus on distributed systems, Kafka-based event-driven architectures, and backend performance optimization to deliver reliable, fast services.

At Freecharge (Axis Bank), I built a reusable common JAR to enable synchronous and asynchronous workflows, cutting service network hops and improving response times by 50–60%. At Lowe’s India, I improved REST API performance by 40% through service and query optimization, and I developed Spring Boot workflows integrated with Kafka-based event processing. I also developed backend microservices and RESTful APIs at Capgemini, optimizing services and resolving production issues to improve system stability.
