What I'm looking for

I'm seeking Frontend or React.js roles in Delhi NCR where I can build scalable, high-performance web applications and responsive user interfaces.

I've built scalable React.js, Next.js, and TypeScript applications at Nubiz Solution Limited, serving more than 10,000 active users across web and mobile experiences.

I developed 30+ reusable UI components and integrated 50+ REST APIs with JWT authentication and role-based authorization. My work reduced development time by 30% and improved load times by 40% through code splitting, lazy loading, and bundle optimization.

I've delivered accounting systems, analytics dashboards, CRUD applications, and real-time trading platforms. On a trading platform, I supported 10,000+ concurrent users and reduced render time by 45% using memoization and virtualized lists.

Before moving into frontend development, I taught computer applications at Rajindra Academy, helping students build practical software and internet skills.
