Foldr

Foldr is a cloud storage platform inspired by Google Drive that allows users to upload files to AWS S3, manage them with folders, mark favorites, share files securely, and restore/delete from trash. The goal was to build a scalable storage product with clean UX and production-level backend patterns.

• Upload files & manage them with a clean file manager UI.
• Create folders and organize content like Google Drive.
• Mark important files as favorites.
• Move files to trash and restore/delete permanently.
• Share files with other users using secure sharing links.
• Preview files in a dedicated viewer page.
• Quickly search and filter files.

• To learn how real-world storage products work end-to-end.
• To build production-level file upload pipelines using AWS S3.
• To understand how to store metadata in MongoDB and sync with S3.
• To practice authentication, authorization and secure access patterns.
• To build a portfolio-worthy project that feels like a real product.

• Built a scalable upload pipeline using AWS S3 + metadata tracking in MongoDB.
• Learned a lot about secure file access, signed URLs, and permissions.
• Implemented file preview navigation similar to Google Drive.
• Improved performance by optimizing server components + caching strategy.
• Learned deployment constraints on Vercel (cookies, CORS, etc.).

• Add folder sharing & role-based access (viewer/editor).
• Add realtime collaboration on shared folders.
• Improve file search with tags and full-text indexing.
• Add file versioning (upload history).
• Add activity logs for every file action.
