At InfraMantra India Pvt. Ltd., I architected and shipped a production real estate CRM Lead Management System that handles thousands of records. I used atomic updates and row-level locking to prevent data conflicts under high concurrency, and reduced query latency by 35% through indexing and MongoDB aggregation tuning.

At Alchemy Software Technologies Pvt. Ltd., I developed healthcare applications for Regeneron, including backend workflows and React.js dashboards. I reduced API response time by 80% with Redis caching, and containerized services for deployment to Kubernetes.
