API Design Principles
Builds scalable, maintainable, and developer-friendly REST and GraphQL APIs using industry-standard design patterns.
The API Design Principles skill provides expert-level guidance for architecting modern web services that are intuitive for developers and optimized for performance. It covers the full lifecycle of API development, from resource-oriented RESTful modeling and HTTP semantics to GraphQL schema-first design and resolver optimization. By implementing best practices for pagination, error handling, versioning, and HATEOAS, this skill helps you create robust backend interfaces that stand the test of time. It is particularly useful for teams looking to standardize their API layer, migrate between paradigms, or eliminate common performance bottlenecks like the N+1 problem using DataLoaders.
