About

I’m a backend developer with 2 years of experience designing and scaling distributed systems. At Kratin, I migrated messaging infrastructure to Azure Event Hub, architected systems handling over a billion events annually, and built reusable libraries to streamline development. I’ve also worked on document intelligence, real-time analytics, and DevOps practices including Docker and CI/CD. Earlier at Hitachi Vantara, I strengthened database performance through optimized SQL queries and delivered robust REST APIs. My passion lies in solving distributed systems challenges and automating workflows to drive efficiency.
