Develop a Digital Asset Management (DAM) system

Our marketing team is drowning in files. Product photos, ad videos, logo variations, brochures, and press kits are scattered across shared drives, chat, and personal laptops, and every new project starts with the question of where the last approved version is. We want you to build a full-featured digital asset management system: a single searchable media library that becomes the source of truth for all our brand visuals and documents. This is not a knowledge base with articles and not a CMS for publishing website pages — it's a repository whose job is to quickly and reliably store, organize, and deliver the asset files themselves. The foundation is search and structure. Each asset needs rich metadata so we can attach tags, categories, campaigns, usage rights, and free-form descriptions, then find the right file in seconds by filtering on these fields. Assets live inside a folder tree that mirrors our team structure, and the system should generate thumbnails and previews for images, videos, and common document formats so the file is recognizable before download. Versioning is essential: when a designer uploads a new video edit, previous versions remain available and clearly marked, and it's always visible who changed what and when. Access rights should determine who can view, download, edit, or delete within each folder, since agencies and freelancers get limited access while employees see more. The last major block is sharing. We need share links through which an external partner can download a specific asset or entire collection without registration, with optional expiration times, password protection, and download limits so nothing leaks endlessly. Propose a clean modern web interface, recommend a stack and storage approach, and describe how you'll handle large files and bulk uploads. — Search by tags and metadata with fast filtering — Folder tree, thumbnails, and preview for photos, videos, and documents — Version history with change log (who changed what) — Role-based rights for each folder: employees, agencies, freelancers — Share links and collections with expiration and password protection — Bulk upload and handling of heavy media files
