Secure Authentication & Role-Based Access Control System

The Problem

The application needed a way to let different types of users (admins, staff, regular users) access different parts of the API — without hard-coding permission checks everywhere in the codebase, and without exposing sensitive endpoints to the wrong users.

The Solution

Designed and implemented a JWT-based authentication system alongside a role-based access control (RBAC) layer in Django REST Framework. Built reusable permission classes so new endpoints could declare 'who can access this' in one line, rather than repeating logic across the app. Combined this with CORS and CSRF configuration to harden the API against common attack vectors.

The Outcome

• ✦Reduced unauthorized-access risk by centralizing permission logic instead of scattering ad-hoc checks across views
• ✦Cut new-endpoint development time significantly since permission classes were reusable
• ✦Documented the entire auth flow in Swagger, which shortened frontend integration time for the team
