API Development
REST and GraphQL API design
API Security Hardening Framework
Harden REST/GraphQL APIs against the OWASP API Top 10 — with authentication patterns (OAuth 2.1, mTLS), fine-grained authorization (RBAC/ABAC), input validation, rate limiting, and threat-model-driven controls that block the specific attack classes your API faces, not generic "enable HTTPS".
API Security Framework
Harden an API against the OWASP API Security Top 10 — with implementation-specific defenses for injection, broken object authorization, excessive data exposure, and mass assignment vulnerabilities that affect production APIs.
GraphQL API Design Framework
Design a GraphQL API — with schema design principles that prevent N+1 queries, mutation conventions that make operations predictable, authorization at the field level, and depth limiting that prevents query complexity attacks.
API Webhooks Design Framework
Design a webhook system — with event schema standards, delivery guarantees, signature verification, retry logic, and consumer-facing registration that makes webhook integrations reliable and debuggable.
API Testing Framework
Build an API testing suite — covering contract testing, integration testing, and load testing with the specific assertions that verify both the happy path and the failure conditions consumers depend on handling correctly.
API Versioning & Evolution Framework
Design an API versioning strategy — distinguishing breaking from non-breaking changes, managing the deprecation lifecycle without breaking existing integrations, and communicating changes to consumers with enough lead time for migration.
API Error Handling Framework
Design an API error handling system — with a consistent error response schema, a machine-readable error code catalog, field-level validation error structures, and error propagation patterns that give consumers actionable information without exposing internals.
API Rate Limiting & Throttling Framework
Implement API rate limiting — selecting the right algorithm for the use case, enforcing limits per identity tier, communicating limits to consumers via headers, and designing the limit structure that protects the service without degrading legitimate high-volume usage.
API Documentation Framework
Write API documentation — with an OpenAPI specification structure, endpoint reference that answers every consumer question without requiring a support ticket, and getting-started guides that get developers to their first successful API call in under 10 minutes.
API Authentication & Authorization Framework
Design an API authentication and authorization system — selecting the right auth mechanism for the use case, implementing JWT or OAuth correctly, and enforcing resource-level authorization that prevents privilege escalation and horizontal access violations.
REST API Design Framework
Design a production-ready REST API — with resource modeling, HTTP method semantics, status code conventions, versioning strategy, and error response standards that create a consistent, predictable interface for API consumers.
