Built enterprise telecom dashboards using React.js, Next.js, and Tailwind CSS, focusing on responsive and accessible UI components with React Hooks. Authored technical specifications and documentation for feature enhancements; participated in Agile/Scrum sprint planning and retrospectives. Improved page load performance by ~25% through rendering audits using React DevTools and Lighthouse/Web Vitals optimization. Reduced redundant API calls by ~30–40% via memoisation, Redux/Context optimization, and Redis server-side caching. Implemented JWT authentication and RBAC across REST API endpoints and UI layers. Conducted UAT for new modules prior to production release to ensure alignment with functional requirements.

Built enterprise telecom dashboards using React.js/Next.js and Node.js/Express.js REST APIs; optimized data persistence across MongoDB and PostgreSQL. Improved page load times by auditing rendering patterns, eliminated re-renders, and reduced backend latency. Cut redundant API calls by 30–40% via memoization, Redux/Context state optimization, and Redis caching. Designed RESTful API endpoints with JWT authentication and role-based access control. Modeled network topology in Neo4j using Cypher queries to power interactive circuit maps and device-dependency graphs. Accelerated sprint delivery by cross-functional collaboration with PMs, designers, and QA; resolved 20+ production bugs.

Developed responsive, user-friendly web interfaces using React.js, Next.js, and Tailwind CSS for enterprise and US telecom projects. Translated UI/UX designs into pixel-perfect, reusable components, ensuring cross-browser and cross-device compatibility. Integrated frontend applications with REST APIs, handling asynchronous data flow and error states. Implemented state management using Redux and Context API for scalable application architecture. Optimized application performance by reducing unnecessary re-renders, improving page load time by ~25% and improving component structure. Collaborated closely with product managers, designers, and backend engineers in an Agile environment. Troubleshot and resolved frontend issues related to UI, performance, and API integration. Contributed to internal dashboards and tools used by enterprise teams.
