I’m a Senior Frontend Engineer with 7+ years of experience building scalable React applications for large enterprise systems. I’ve led frontend modernisation efforts in compliance-critical, high-availability environments—especially for financial services.

At Tata Consultancy Services, I led the frontend modernisation of a high-traffic US banking portal, migrating from legacy to a React-based micro-frontend architecture. I built a reusable React/JS/CSS component library used across 10+ micro-frontend modules, reducing duplicated code and speeding up feature delivery.

I’m deeply hands-on with state management and performance optimisation, introducing Zustand to remove prop-drilling patterns and applying React.memo, useMemo/useCallback, lazy loading, and Webpack code splitting. I also architected REST API integration layers with standardised error handling and retry logic.

To keep quality high, I authored Jest/RTL unit tests and Playwright E2E suites, strengthening release confidence in distributed agile teams. Before that, at SADA (formerly Bytewave Digital), I built scalable React SPAs, improved UI responsiveness, and supported consistent design systems—earning multiple TCS recognitions along the way.
