User Management Development

I need a clean, secure user-management module that I can drop into an existing web application. Core features must include:

• User registration and email-password login
• Role-based access control with custom roles (I will start with admin, HR, manager and user, but the system should let me add or adjust roles later)
• Edit and delete functions for individual accounts

Everything should be coded with best-practice password hashing, session handling, and clear error messages. Keep the architecture flexible so I can bolt on multi-factor or social logins in the future without rewriting the core.

Deliverables
1. Fully documented source code (backend and frontend)
2. Database schema or migration scripts
3. Setup instructions that let me spin it up locally in a single command
4. A short test sheet showing successful registration, login, role assignment, edit and delete actions for each of the sample roles

I will test by installing on a fresh machine, running your setup script, and stepping through the test sheet. Once everything passes, the milestone is complete.
