API contract design
Define resources, request and response shapes, and a versioning strategy upfront, documented in OpenAPI or a GraphQL schema so consumers have a real contract to build against.
API Development
APIs other teams can actually depend on.
REST and GraphQL API design and development with authentication, versioning, and error handling built for consumers you don't control.
Book a discovery callTHE BUSINESS NEED
Start with the problem.
Build what matters.
An API used by more than one team or an external partner needs to behave predictably even when its consumers make mistakes, retry requests, or move slower than you'd like to adopt a breaking change. That means authentication, versioning, and error responses need to be designed deliberately — not whatever fell out of the first implementation.
How we approach it
We design the API contract — resources, error shapes, versioning strategy — before writing the implementation, since that contract is what other teams build against and is expensive to change later. Idempotency keys, rate limiting, and consistent error formats are built in from the start rather than retrofitted after the first production incident caused by a retry storm.
CAPABILITY IN DETAIL
What this means in practice.
Specific engineering work, connected to a business need.
Authentication and authorization
Implement API key, OAuth 2.0, or JWT-based authentication matched to whether consumers are internal services, partner integrations, or end-user applications.
Reliability patterns
Add idempotency keys for retried write operations, rate limiting, and structured error responses that give calling code enough information to actually handle failures.
Versioning and deprecation
Plan a versioning approach that lets the API evolve without breaking existing consumers overnight, with a defined deprecation process for changes that must eventually happen.
WHERE IT CAN HELP
Problems worth solving.
Illustrative engagement types, not claims about previous projects.
- Exposing internal functionality to a partner or third-party integration
- Building a public or partner-facing API from scratch with a real versioning strategy
- Hardening an existing API that breaks under retries or lacks consistent error handling
BEFORE WE BEGIN
Questions, answered.
REST or GraphQL — which is right for us?
REST tends to fit well-defined resource-oriented APIs, especially for external or partner consumers; GraphQL fits products where frontend teams need flexible, evolving queries against a complex data graph. We recommend based on your consumers, not a default preference.
How do you handle breaking changes?
Through explicit versioning and a deprecation window communicated to consumers, rather than changing behavior under an existing version and hoping nothing breaks.
Can you document an existing, undocumented API?
Yes, we can reverse-engineer and document current behavior into an OpenAPI specification as a starting point before making further changes.
