Backend API Development Service
REST and GraphQL API development with data models, validation, authentication, and integration-ready back-end structure.
What I provide
I build backend APIs that expose clear resources, handle validation, connect to a database, and support authentication when the product needs user-specific actions.
When this service fits
It fits a front end or mobile app that needs a server, an admin surface that needs real data, or a product that should define its API before the final UI is complete.
How the service is delivered
I define the resources and operations first, then implement routes or GraphQL resolvers, service logic, models, error handling, and run documentation.
Portfolio evidence
movies-api is the API-only proof point, while event-booking-platform and recipes-social-mobile-app show GraphQL and REST-style backend work inside fuller products.
