Message

At Virtusa, I engineered a scalable, event-driven Email Notification Engine using Node.js and Golang microservices. I also developed React.js and TypeScript administrative portals and AWS Lambda handlers for webhook workflows.

At IBM, I designed backend microservices and built React.js applications while maintaining legacy AngularJS dashboards. I also developed REST, GraphQL, and gRPC APIs and containerized applications with Docker and Kubernetes.

At LTI Mindtree, I spearheaded a four-engineer squad building a security automation platform that identified vulnerabilities across code repositories. I integrated automated code analysis into Jenkins and GitLab CI/CD pipelines.

Across roles at Capgemini, Mindtree Pvt Ltd, Wipro Limited, and Neobric IT Solutions, I worked on real-time audio and screen sharing, smart insurance applications, blockchain platforms, and decentralized storage.
