I've built enterprise web applications for Wipro, Bajaj Finserv, and KPMG India, delivering React and Node.js solutions for banking, financial services, and audit teams.

At Wipro, I architected six scalable React 18 modules, reduced re-renders by 40%, improved Lighthouse scores by 30%+, and cut deployment cycle time by 35% through Jenkins CI/CD improvements. I also built Node.js and Express.js microservices that reduced API latency by 25%.

At Bajaj Finserv and KPMG India, I delivered MERN features for loan processing, account management, and audit workflows, securing over 1M transactions with JWT authentication and RBAC. I've also created reusable component libraries, mentored junior developers, and improved application responsiveness through performance-focused engineering.
