As a Full-Stack Developer on Dupely, I helped build a browser extension that enables shoppers to discover alternative products and potential savings in real time while browsing online retailers. I worked across both the frontend and extension architecture, developing user-facing experiences with React while integrating backend services, authentication systems, and real-time data streaming.

My responsibilities included building the Side Panel UI, implementing authentication flows, profile management, wishlist and history features, analytics tracking, and retailer-aware product detection. I also contributed to the extension infrastructure, including Socket.IO communication, caching strategies, state management, API integrations, and cross-browser compatibility. A key focus was ensuring reliable real-time updates and seamless user experiences across Chrome, Safari, and other supported browsers.

By combining frontend development, backend integration, and browser extension architecture, I helped deliver a scalable, responsive, and production-ready shopping assistant used across multiple e-commerce platforms.
