I have experience developing backend and full-stack applications involving authorization systems, user permissions, workflow controls, auditability, and secure administrative operations using TypeScript, Node.js, React, MongoDB, and SQL databases.

A significant part of my experience comes from building multi-tenant ERP systems where users, roles, permissions, approval workflows, and multi-tenant access restrictions must be enforced consistently across multiple modules. This closely aligns with RBAC requirements, including permission inheritance, role management, administrative controls, auditability, and access validation for sensitive operations.

For this issue, I would focus on building a maintainable and secure role-based access control system with clear role definitions, permission enforcement, role hierarchy, administrative controls, audit logging, and immediate revocation capabilities. I would prioritize modularity so the access-control layer can be reused consistently across multiple contracts.

I would also develop comprehensive tests covering role assignment, permission validation, hierarchy behavior, revocation scenarios, emergency administration controls, and edge cases to ensure reliability and security.
