API development
REST + GraphQL, OpenAPI, versioning, rate limiting
APIs for external clients, mobile apps, B2B partners. Properly documented, versioned, with multi-strategy authentication and rate limiting from day one.
- 01
REST + GraphQL API design
REST where simplicity matters, GraphQL for complex queries with n+1 avoided. Pydantic / Zod models as the source of the contract.
- 02
Auto-generated OpenAPI documentation
Swagger UI / Redoc / Scalar generated from code. Error codes, examples and schema stay current, not out of sync.
- 03
Proper versioning (v1, v2)
Deprecation policy with sunset headers, migration guides, overlap period. Clients know before anything breaks.
- 04
Rate limiting + caching
Sliding window per API key or per IP. Redis cache for hot read endpoints. CDN-level caching where possible.
- 05
Multi-strategy auth
JWT RS256 for SPAs, API keys for B2B integrations, OAuth2 for third-party apps. Refresh tokens with rotation.
