Service

Backend & API Engineering

Servers, services and APIs built around your domain, designed to stay correct and fast as load, features and integrations grow.

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.

  1. Map the domain

    The data, the boundaries between services and the consumers of each endpoint identified before anything is designed.

  2. 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.

  3. Build and test under load

    Implementation with automated tests and the failure paths exercised deliberately, not assumed to work because the happy path does.

  4. 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

No published case studies yet

We publish case studies only once the client has approved the wording, and none are cleared for publication yet. Ask us directly and we'll talk you through comparable work under NDA.

Draft copy

Include the country code.

Optional, but it helps us propose something realistic. Any currency, and a range is fine.

What needs to exist, what problem it solves, and any constraints we should know about — compliance, deadlines, systems it has to work with.

Commercially sensitive details are best left out of a web form — tell us enough to scope it and we'll take the rest over a call.

Other capabilities

  • 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.
