RBAC System - Role-Based Access Control

Managing granular user permissions and securing system resources across multi-user web applications is complex, error-prone, and frequently leads to security vulnerabilities or fragmented code when access logic is hardcoded without clear separation of concerns.

The strategy focused on engineering a centralized Role-Based Access Control (RBAC) architecture that cleanly decouples authentication from authorization, enabling administrators to dynamically create roles, assign granular permissions, and enforce consistent access policies across both client views and server endpoints.

The interface was designed around an administrative dashboard prioritizing clarity and control, featuring structured data tables for user management, intuitive toggle-based permission matrices, and distinct visual badges for active roles and authorization states.

Developed as a full-stack application using React for the modular administrative UI, Node.js and Express for RESTful API services with custom authorization middleware, and SQLite for relational data persistence across users, roles, and assigned permissions.

Delivered a secure, functional RBAC system that reliably enforces route and resource protection, streamlines user permission management, and serves as an extensible blueprint for enterprise access control workflows.
