C.R.A.C.K Project Backend

Project Overview

C.R.A.C.K is a comprehensive educational platform built with Nest.js backend, featuring secure authentication systems, role-based access control, and efficient data management using Prisma ORM with PostgreSQL.

This backend system handles user authentication, course management, and administrative operations with a focus on security, scalability, and maintainability.

Key Responsibilities

• Secure Authentication System

  Engineered a secure authentication system using Passport-JWT and Bcrypt to protect sensitive user data and manage session persistence.

• Role-Based Access Control (RBAC)

  Developed a role-based access control framework with custom guards to strictly differentiate administrative privileges from student access levels.

• Relational Database Schema

  Architected a relational database schema using Prisma ORM and PostgreSQL to efficiently manage many-to-many relationships between users and courses.

• Data Validation Pipes

  Created automated data validation and transformation pipes globally to ensure API reliability and maintain consistent data integrity across all endpoints.
