Assignment Grader

Overview

Gradify – A Teacher-Student Assignment Grading System 📚✨

Gradify is a web-based platform that simplifies assignment management and grading for teachers and students. Teachers can create assignments, track submissions, and grade efficiently, while students can submit their work via Google Drive or PDFs and view their grades seamlessly. 🚀

Architecture

Gradify follows a Three-Tier Architecture with a RESTful API:

• Frontend (Angular 19) – Handles UI/UX and communicates with the backend via REST APIs.
• Backend (ASP.NET Core) – Implements business logic, authentication, and API endpoints.
• Database (SQL Server) – Stores assignments, submissions, and user data securely.

This architecture ensures scalability, security, and flexibility, allowing future integrations with mobile apps or third-party services. 🔐🚀
