Builds GraphQL APIs with schema design, resolvers, DataLoader for N+1 prevention, error handling, and optimizations using Apollo Server (JS) or Graphene (Python). Useful for flexible queries, REST migrations, or subscriptions.

Build GraphQL APIs with proper schema design, resolvers, and performance optimization.
Guides GraphQL API development: schema design with Relay connections and payloads, thin resolvers, N+1 detection/fixes via DataLoader, subscriptions over WebSocket/Redis, federation, query depth/complexity limits.
Covers GraphQL schema design, resolvers, DataLoader for N+1 prevention, federation, subscriptions, and client integration with Apollo/urql.
Designs GraphQL schemas with Apollo Federation, implements resolvers with DataLoader, and optimizes query performance. Invoke for schema design, federation directives, and real-time subscriptions.
