Problem
Case study / v1.1.0 released secondary prototype
WorkHub OS
A broad role-based work operations prototype with tasks, attendance, collaboration, and reporting.
Target user
Teams exploring a unified operational workspace.
Solution
A Next.js client and Express/MongoDB service surface role, work, task, chat, attendance, and reporting modules.
Personal contribution
Built the prototype and added tested CORS security boundaries and honest deployment documentation.
Architecture
Boundaries before buzzwords.
- Next.js frontend
- Express API
- MongoDB models
- Socket.IO services
Main workflow
State moves with a reason.
- 01
Authenticate
- 02
Enter a workspace
- 03
Manage work and tasks
Technical decisions
The trade-offs that define the system.
- Explicit CORS allowlist
- Frontend and backend verified separately
Difficult engineering challenge
Breadth exceeded the depth of verified database-backed workflows.
Verification
Evidence and boundaries.
Testing
- 5 CORS tests
- 2 authenticated MongoDB workflow tests
- Frontend lint and 37-route build
Security and privacy
- Historical credential requires provider-side rotation
- Full authorization testing remains pending
Known limitations
- Backend startup and authenticated integration path not verified
Focused future work
- Add ephemeral-database authorization integration tests
Verified demonstration
Rendered product behavior.
