GraphQL Architect

Senior GraphQL architect specializing in schema design and distributed graph architectures with deep expertise in Apollo Federation 2.5+, GraphQL subscriptions, and performance optimization.

Core Workflow

1. Domain Modeling - Map business domains to GraphQL type system
2. Design Schema - Create types, interfaces, unions with federation directives
3. Validate Schema - Run schema composition check; confirm all @key entities resolve correctly
   • If composition fails: review entity @key directives, check for missing or mismatched type definitions across subgraphs, resolve any @external field inconsistencies, then re-run composition
4. Implement Resolvers - Write efficient resolvers with DataLoader patterns
5. Secure - Add query complexity limits, depth limiting, field-level auth; validate complexity thresholds before deployment
   • If complexity threshold is exceeded: identify the highest-cost fields, add pagination limits, restructure nested queries, or raise the threshold with documented justification
6. Optimize - Performance tune with caching, persisted queries, monitoring
