Service
Backend & API Engineering
Overview
A backend usually fails quietly at first — a query that gets slower every quarter, an endpoint three other services depend on that nobody documented, an integration that works until the third party changes something without warning. By the time it is loud, the fix competes with everything else on the roadmap.
We build and rebuild backends with the data model, the failure modes and the access boundaries treated as the actual design, not the plumbing underneath it. Authentication, authorisation and audit logging are specified alongside the endpoints, not bolted on when a customer asks about them.
Capabilities
What backend & api engineering covers
API design and delivery
Services and endpoints designed around your domain, with clear versioning and error contracts so consumers can build against them with confidence.
Systems integration
Connecting the tools and third parties you already depend on, with explicit, tested handling for the day one of them is slow or down.
Performance and scaling
Finding the query, the lock or the hot path that is actually costing you latency, and fixing that rather than the infrastructure around it.
Access, audit and security
Authentication, authorisation and audit logging treated as first-class requirements, reviewed the same way the business logic is.
Process
How we deliver it
The four stages backend & api engineering moves through, and what you have at the end of each.
Map the domain
The data, the boundaries between services and the consumers of each endpoint identified before anything is designed.
Contracts before code
API contracts and error cases agreed in writing — the thing that is cheap to change now and expensive to change once something depends on it.
Build and test under load
Implementation with automated tests and the failure paths exercised deliberately, not assumed to work because the happy path does.
Document and hand over
API documentation, runbooks and a walkthrough, so your team can extend or debug it without calling us.
Copy pending founder sign-off
PRD §8 requires the exact scope of each service to be confirmed before final copy. Outstanding for this one:
- Preferred language and framework defaults for new backend builds
- Standard support and maintenance terms offered after handover

System Architecture
The data model, service boundaries and trust boundaries decided and written down before the build, sized for the load you actually expect.
Payment & Fintech Integrations
Payment, collection and disbursement flows integrated end to end, with every transaction landing in a known, reconciled state.
UI/UX Design
Research, interface design and reusable design systems — accessible by construction, not by later remediation.
