Balbir Kaur

I am a Senior Frontend-focused Engineer with 4+ years building scalable, high-performance web applications using React, Next.js, and TypeScript. I specialize in component-driven architecture, frontend performance optimization, and delivering enterprise-grade solutions for fintech and banking platforms.

At Cognizant I lead frontend development, own frontend architecture, and drive reusable component design and performance standards, achieving Lighthouse scores of 90+. I collaborate closely with product, backend, and QA teams in Agile delivery to ensure reliable releases.

My hands-on experience includes integrating GenAI capabilities—RAG, LangChain, embeddings, FAISS, and Azure OpenAI—to build context-aware chatbots and knowledge-grounded assistants that improved response relevance substantially. I also contribute backend skills with Node.js/Express and Python for end-to-end solutions.

I am results-oriented, focused on measurable performance gains (code-splitting, lazy loading, memoization) and rapid, maintainable development. I seek opportunities where I can lead frontend architecture, apply GenAI effectively, and drive impactful product outcomes.
