Work Experience

Frontend Developer — React.js | System Engineer

Tata Consultancy Services (TCS)

Nov 2021 - Oct 2025 Hyderabad, India
  • Architected and shipped React.js modules for a national government portal that scaled from 50K to 500K active users; applied code splitting and lazy loading to reduce initial bundle size and improve Time -to-Interactive by eliminating render-blocking resources.
  • Designed a reusable component library of 40+ components — including form controls, data tables, and modals — adopted across 4 enterprise applications, cutting per -dashboard build time by 30% and enforcing a unified design language across teams.
  • Built a real -time chat interface and a smart search module with debounced auto -suggestions for a 200K -user insurance portal, directly contributing to a 25% uplift in measured user engagement metrics.
  • Developed interactive BI dashboards in Recharts and Highcharts with drill -down filters and live data feeds for a telecom analytics team, replacing static reports and reducing time-to-insight for business stakeholders.
  • Implemented JWT-based authentication with RBAC and protected route guards, securing access across 3+ multi - role enterprise applications and eliminating unauthorized route access.
  • Centralized all REST API communication through Axios interceptors — handling token refresh, error normalization, and request cancellation — reducing duplicate API-handling code by an estimated 40% across the codebase.
  • Drove frontend performance improvements using useMemo, useCallback, and useRef to eliminate unnecessary re- renders; combined with pagination and infinite scroll to keep large list components under a 100ms interaction response time.
  • Participated in 2 -week Agile sprints; led unit testing with Jest and React Testing Library, maintaining >80% code coverage on owned modules; contributed to estimation sessions and design discussions.
