Nancy Kumari Terapalli

I build React.js applications that remain fast, maintainable, and reliable as products grow. Over the past 4 years at Tata Consultancy Services, I've delivered enterprise web applications across government, insurance, and telecom domains, translating complex business requirements into intuitive user experiences.

One of my key contributions was designing a reusable React component library that became the foundation for 4+ applications, reducing dashboard development time by 30% while ensuring a consistent user experience across teams. I also developed scalable modules for a national government platform supporting growth from 50,000 to over 500,000 active users by applying code splitting, lazy loading, and performance-focused rendering strategies.

I enjoy solving problems that directly improve product quality. From implementing real-time chat and intelligent search with debounced suggestions that increased user engagement by 25%, to building JWT authentication, role-based access control, and centralized API handling with Axios interceptors, my focus is creating secure, responsive, and scalable frontend systems.

Beyond writing code, I enjoy collaborating with designers, backend engineers, and product teams to ship features that balance performance, usability, and long-term maintainability. I'm currently looking for opportunities where I can contribute to building modern React products used by people at scale.
