THE PROBLEM
The interfaces between systems are where estimates go wrong and where production incidents start. They are also what partners and internal teams judge you on.
What we usually hear- Undocumented interfaces that only one person understands
- Breaking changes discovered by consumers in production
- No rate limiting or abuse protection on public endpoints
- Integrations that fail in ways nobody planned for
HOW WE APPROACH IT
Engineering, not guesswork
We design the contract first, with versioning and a deprecation policy agreed before anything is built, so consumers are never surprised.
Authentication, rate limiting and abuse protection are part of the design rather than added after an incident.
We test against real third-party behaviour, including their failure modes, not just the happy path in their documentation.
WHAT YOU RECEIVE
Deliverables
- API design with versioning and deprecation policy agreed up front
- Authentication, rate limiting and abuse protection
- Published documentation and a working sandbox
- Integration testing against real third-party behaviour
WHAT CHANGES
Business outcomes
- Interfaces documented well enough to integrate without a call
- Changes shipped without breaking consumers
- Public endpoints protected against abuse
- Integrations that degrade predictably
TECHNOLOGY
What we typically build with
Selected against your constraints and your team's ability to maintain it — not against fashion.
- Node.js
- TypeScript
- Python
- REST
- GraphQL
- OpenAPI
- PostgreSQL
- AWS
HOW WE DELIVER IT
The same five phases, every time
See the full twelve-stage process for what each phase produces.
Discovery
We map the business problem and define success in measurable terms.
Architecture
Technology and data decisions made against your constraints, documented with reasoning.
Design
Journeys and interfaces resolved on screen, including everything that goes wrong.
Engineering
Short cycles ending in working software, reviewed and tested before it merges.
Deploy & Scale
Automated release, monitoring in production, and support as usage grows.
QUESTIONS
About api development & integration
REST or GraphQL?
REST for most cases; GraphQL where clients genuinely need to shape their own queries across a complex graph. The wrong choice adds cost on both sides.
Can you document an API we already have?
Yes. We map actual behaviour rather than intended behaviour — the two frequently differ — and publish documentation plus a working sandbox.
How do you handle versioning?
Explicit versions with an agreed deprecation window, so consumers have time to migrate.
RELATED SERVICES
Often needed alongside this
Cloud Infrastructure & DevOps
Infrastructure treated as part of the product — provisioned as code, deployed automatically, and observable in production.
Enterprise Systems
Systems that carry real operational load — role-based access, audit trails, integrations and the reliability an organisation depends on.
Business Process Automation
Replace the manual work your team repeats every week with systems that run themselves and report when they cannot.
