Yes. I can implement secure authentication using JWT, role-based access control (RBAC), password hashing, and refresh tokens.
Will the API be documented?
Yes. Standard and Premium packages include interactive API documentation using Swagger/OpenAPI.

I work with PostgreSQL, MySQL, MongoDB, and SQLite depending on your project requirements.
Can you deploy the backend?
Yes. I can help deploy your application using Docker or cloud platforms. Deployment can be discussed based on your requirements.
What do you need before starting?
Please provide your project requirements, API specifications (if available), database preferences, and any existing code or documentation.
Can you build a complete backend from scratch?
Yes. I can design the database, develop the REST API, implement authentication, integrate the database, document the API, and deliver a production-ready backend.
