Overview
We define types and relationships that reflect your domain, implement resolvers against your databases or existing services, and add field-level authorization where data sensitivity requires it. Attention goes to query depth limits, batching to avoid N+1 database calls, and clear error handling for clients. The result is a schema and server code in your repository, tests for key queries and mutations, and documentation your frontend team can explore through introspection.
Benefits
Clients fetch exactly the data needed
Single typed schema across data sources
Field-level access control
Fewer round trips for frontend apps

Service FAQ
Yes. Resolvers can call existing REST services, so you can introduce a unified GraphQL layer without rewriting the underlying backend.
