Custom Management System Development

I need a modern, responsive management system built from the ground up. The core features I want are:

• User management with secure authentication and role-based permissions
• Task management so my team can create, assign, and track work items in real time
• Analytics and reporting dashboards that surface key metrics at a glance

My preferred stack is React on the front end, powered by a Node.js back end with a clean, well-documented API layer. I expect clean architecture, scalable database design, and code that is easy to maintain and extend.

Key points to keep in mind:
• Mobile-first, responsive UI
• Clear separation of front-end, API, and data layers
• Strong emphasis on security and data validation
• Well-written README and inline comments so future developers can onboard quickly

Please outline your proposed approach, estimated timeline, and any relevant examples of similar systems you’ve shipped.
