What I'm looking for

I want to work with an esteemed organization that supports knowledge sharing in a strong environment. I’m driven to prove my ability through quality products—collaborating in teams, learning continuously, and delivering high-performance UI under pressure.

I’m a Senior UI Lead with 15+ years of IT experience, including 8+ years developing user interfaces with React.js. I bring hands-on experience with React (17.x/18.x) and Angular (6, 8, 12, 13), with a focus on performance, reliability, and maintainable front-end architecture.

In my current role at TATA Consultancy Services, I developed and managed high-performance, responsive interfaces for financial applications, emphasizing data accuracy, regulatory compliance, and security. I build complex reusable components using React 18+ and TypeScript, apply state management with Redux, integrate banking APIs, and improve maximum uptime through testing and code optimization.

Previously at HCL Technologies and earlier roles, I led UI development across multiple domains—from e-commerce-like shopping cart experiences to CSV-driven analytics workflows and STB UI development. I also enjoy knowledge sharing and consistently deliver under pressure by collaborating effectively, learning quickly, and strengthening teams through quality-focused, production-ready UI.
