I've built full-stack web platforms at Tata Consultancy Services and Coding Club India, using React.js, Next.js, Node.js, TypeScript, and PostgreSQL to deliver reliable products at scale.

At Tata Consultancy Services, I engineered a centralized analytics dashboard that reduced reporting turnaround by 40% and improved customer satisfaction by 15% across three business units. I also migrated a legacy enterprise application to Google Cloud Platform, reducing operational costs by 20% and deployment time from six hours to two.

At Coding Club India, I built a real-time React testimonial component that increased engagement and feedback submissions by 40%, tuned backend APIs to reduce page latency by 250 milliseconds, and established an interactive course platform for 2,000+ learners.

I've also delivered payment, publishing, video, and recommendation products, including Nexis Pay, which supported 25,000+ peer-to-peer transactions with 99.9% uptime. I enjoy building production-ready APIs, databases, and user experiences that improve performance, engagement, and conversion.
