You will get a secure JWT authentication system with role based access control
Project details
You will get a production-ready JWT authentication and authorization system — secure, tested, and built to protect your application and users from day one.
Authentication is the most critical part of any application. A weak implementation exposes users to breaches and unauthorized access. I build auth systems that follow security best practices — not shortcuts.
My production experience includes JWT authentication with role-based access control across fintech and SaaS backends — zero security incidents across all deployments.
What you get:
• JWT access tokens + refresh token rotation
• Bcrypt password hashing (12 salt rounds)
• Role-based access control (RBAC) with protected middleware
• Rate limiting on login endpoints (brute-force prevention)
• Input validation and sanitization
• TypeScript or Python typed source code
• Full test suite (95%+ coverage)
Whether you need basic login/signup, a multi-role admin system, or OAuth social login — I will build it secure and maintainable.
Portfolio section has live code samples.

Steps for completing your project
After purchasing the project, send requirements so Anthony can start the project.
Delivery time starts when Anthony receives requirements from you.
Anthony works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements & Architecture Review
I review your stack, user roles, and security requirements then propose the auth architecture — token strategy, role structure, and security measures — before writing any code.
Core Authentication Build
I implement JWT access/refresh token system, bcrypt password hashing, login/signup endpoints, token validation middleware, and secure token storage strategy.
