I'm excited to present Stack, a full-stack web application designed to simplify link management and encourage collaboration through secure and efficient features. At its core, Stack offers smooth user signup and login powered by JWT-based authentication, ensuring data security and user privacy. A standout feature of this app is its time-limited invite system, which allows users to generate invite links valid for one hour-ideal for temporary collaboration or access control. The platform also enables users to save important links instantly, organize them using tags, and navigate through a smart dashboard with dedicated sections for better clarity. Powerful tools like quick search and filtering, as well as on-demand detailed views, make it easy to retrieve and manage information. The minimal, customizable interface ensures a distraction-free experience tailored to user preferences. Built with React and Tailwind CSS for a sleek, modern front end, and backed by a Node.js/Express server deployed on Render, Stack currently targets desktop users. This project reflects my growing experience in full-stack development, integrating frontend design, backend architecture, and user-centric functionality.
