01
Discovery
Consumers and use cases define the contract. Errors get a taxonomy.
Service
API Development
API development focuses on contracts teams can rely on—versioning, validation, auth, and documentation that stays true to production behavior.
Problems this work usually addresses
- Breaking changes without notice
- Undocumented error shapes
- Clients reimplementing business rules
Who benefits most
Product teams exposing capabilities to mobile apps, partners, or internal services.
Typical outcomes
- Stable contracts between systems
- Safer integrations
- Less brittle sync work
Technical approach
02
Design & architecture
We implement auth, pagination, idempotency keys where needed, and examples.
03
Build, test, and handoff
Contract tests and changelog discipline protect clients.
Architecture considerations
Resource-oriented or RPC-style based on clients. Gateway concerns stay separate from domain services.
Security
Scoped credentials, rate limits, and careful CORS. Partner keys rotate.
Scaling
Caching and pagination first. Graph complexity only when justified.

Common challenges
- • Hidden N+1 queries
- • Chatty mobile clients
- • Missing idempotency
Frequently asked questions
REST or GraphQL?
REST/JSON for most product APIs. GraphQL when many clients need flexible selection and the team can own the complexity.
