Developed foundational file upload functionality for the HackBeanpot/core repository, focusing on creating a scalable framework to support secure and testable user experiences. Leveraging TypeScript, Node, and React, the work introduced reusable UI components and preview features, along with stubs for upload and download URLs to facilitate early validation. A dedicated demo and testing page was implemented to enable rapid feedback and iteration without requiring backend dependencies. This approach established a robust pattern for asset handling and preview, laying the groundwork for smoother backend integration and accelerating future feature development across teams. No major bug fixes were included in this scope.
