Project description:
"I’m requireing a web-based document controller that mirrors the simplicity and rigour of Oracle Aconex. The platform must let project managers, team members and clients upload and manage PDF and drawing files from any device, then guide those files through a clear review cycle.

Core flow
A user uploads a document, the system stamps a unique version, and selected reviewers can leave threaded comments directly on the file. When all feedback is in, the same screen offers a single-click approve or reject action that automatically advances—or rolls back—the version. Every change must be logged so we can trace who did what and when.

What matters most
• Robust version control with an immutable audit trail
• In-document commenting that feels as easy as leaving a note in Adobe or Bluebeam
• Configurable approval workflow (single step or multi-step)
• Simple permissions so each role—manager, team member, client—sees only what they need

Deliverables
1. A responsive web application (frontend + backend) running in a test environment
2. Database schema and migration scripts for versioning and permissions
3. API documentation so our internal systems can pull status updates
4. Deployment guide so we can move the build to our own cloud instance

Acceptance criteria
• I can upload a PDF, users will reviewers and watch the files from “Pending” to “Approved” with every action captured in the log.
• When I open an older revision, the system flags that a newer one exists and links to it.
• Non users are unable to see the document in search or download it directly.

If you’ve engineered similar control systems—or integrated tools like AWS S3, Azure Blob Storage, React, Angular, Node.js or .NET for secure document handling—let’s talk. Clean, maintainable code and clear documentation will be the key to winning this project." (client-provided description)
