I build backends for platforms where several kinds of users share one product: customers, partners, staff and admins, each with their own permissions and their own view of the data.

What you get:

• A REST API with role-based access control, so each role reaches only its own routes and data • Authentication with JWT, OTP verification and password flows • Database design and migrations, on PostgreSQL or MySQL • An admin panel to manage users, content and the data behind the product • Real-time features where they help: chat, notifications, live status • File and image upload to S3 or your own server • Swagger documentation for every endpoint • Deployment to your server with Docker, SSL and backups

I recently built exactly this for Armorix, a vehicle protection platform with four roles and around 30 database models, as the main backend developer on a team of four.

Tell me what your product does and who uses it, and I'll come back with a plan and a fixed quote.
