Context
The situation and the problem
Previous-year examination papers at VIT were scattered across seniors, messaging groups, personal drives and disconnected resources.
Students needed a reliable way to reach the right paper for a subject and exam, while maintaining a fast-growing collection manually was becoming increasingly difficult.
Approach
The decision behind the experience
The architecture follows one core requirement: a student should reach the right paper as quickly as possible. Resources are organised around academic context instead of behaving like generic file storage.
A service-oriented backend, operational administration and collaborative content model allow the collection to grow without sacrificing discoverability or reliability.

Product
What we designed and built
We built a complete academic platform rather than a static file repository.
The system combines the student application, authentication, resource discovery, REST APIs, backend services, database architecture, administration tools and AWS infrastructure required to operate at campus scale.
