&Developed and maintained user-facing features using React.js, TypeScript, JavaScript (ES6+), HTML5, CSS3, and modern UI libraries such as Bootstrap, Material UI, and Tailwind CSS.

&Built reusable, modular React components and implemented micro-frontend architectures for scalable, maintainable enterprise applications.

&Applied advanced performance optimization techniques including React.memo, useMemo, useCallback, virtualization (react-window), lazy loading (React.lazy, Suspense), and Webpack code splitting to enhance rendering speed and reduce load times by up to 60%.

&Managed complex state management workflows using Redux Toolkit, Redux Thunk, Redux Saga, and useQuery Hook, enabling robust handling of asynchronous data flows and real-time UI updates.

&Designed and developed responsive, cross-browser-compatible user interfaces, ensuring optimal rendering and adherence to WCAG accessibility standards.

&Designed Node.js server-side applications with scalable architectures, implementing asynchronous patterns (Promises, async/await, EventEmitter), optimizing performance under high concurrency.

&Developed reusable middleware in Node.js for tasks like authentication, logging, validation, and error handling to standardize and simplify backend logic.

&Wrote unit and integration tests using Jest, ensuring high code coverage (80%+)

Application Development Senior Analyst
