Comprehensive School ERP Development -- 2

I need an end-to-end School Management ERP that brings three core modules together under one roof and makes life easier for everyone on campus. The system must offer:

• Student Information System
• Attendance Management
• Gradebook Management

Each module should present information differently to Students, Teachers, and Administrators, so solid role-based permissions are essential. The platform also has to plug into our existing school database—no data loss, no double entry, just a clean bi-directional sync.

What I expect from you: a modern, responsive web application (Laravel, Django, Node, or any comparable framework you can justify), clean and well-commented code, and a deployment that works smoothly on our VPS. Include automated tests and an installation guide so we can maintain the system in-house.

Acceptance criteria
• All three modules work as described for every role
• Live integration with the current database is demonstrated without breaking legacy data
• Test coverage of at least 95 % for critical paths
