About this gig
BASIC Authentication Setup
Best for clients who need a secure and functional authentication solution without complex architecture. Includes login endpoint (username/password), JWT authentication (access token), token validation, basic role-based access (e.g. ADMIN / USER) with customizable roles, REST API developed in Java (Spring Boot), and basic README documentation.
STANDARD API Gateway with Authorization
Best for clients who already have backend services and need a real API Gateway. Includes everything in Basic, plus: API Gateway as a single entry point, JWT validation on every request, standardized error handling (401 / 403 / 500), scalable-ready project structure, and clear documentation of authentication and proxy flow.
PREMIUM Enterprise-Ready API Gateway
Best for companies or startups that require security and scalability. Includes everything in Standard, plus: integration with Active Directory / LDAP or existing databases, production-ready configuration, detailed architecture and flow diagrams, and post-delivery support (minor configuration changes, small bug fixes, and integration adjustments).

FAQ
What is considered a revision?
A revision includes minor adjustments such as configuration tweaks, small fixes, or documentation updates based on the original scope. Revisions do not include new features, new endpoints, new services, architecture changes, or additional authentication methods. These require a new order.
What do I need to provide before starting?
Authentication requirements (users, roles, flows), existing backend endpoints (if applicable), environment details (dev / test / prod), any specific security constraints. Delays in providing this information may affect delivery time.
Can you integrate with my existing system or database?
Yes, only in the Premium package or via a custom offer.
Do you deploy the service to production?
No. I deliver production-ready code, configuration, and documentation, but deployment is not included unless explicitly agreed as an extra service.
Do you provide post-delivery support?
Yes, limited support is included depending on the package: clarifications, minor configuration adjustments, bug fixes related to delivered scope New features or major changes are not included.
Is this service suitable if I don’t know exactly what I need?
If your requirements are unclear, please contact me before ordering. I’ll help you: choose the right package, avoid unnecessary costs, define the correct scope This ensures a smooth and successful delivery.
