SERVICE

Backend & API Engineering

Connect your products, data and business rules. We build backend services and APIs that make integrations easier to manage and operational issues easier to trace.

Explore what we can build

WHEN IT FITS

Start with what needs to change

Keeping business rules consistent

Bring shared rules into clear services instead of duplicating them across applications.

Connecting external systems

Design integrations with validation, retry rules and useful diagnostics.

Controlling access to data

Define permission boundaries across people, services and organisations.

SOLUTION SCOPE

What we can build together

Choose the capabilities your project needs. We agree the priorities and boundaries before development.

REST & GraphQL APIs

Expose predictable contracts for web, mobile and partner applications.

Data modeling & persistence

Structure records and relationships around business rules and data access patterns.

Authentication & authorization

Enforce identity, roles and resource-level access on the server.

Third-party integrations

Connect partner APIs and webhooks with explicit failure handling.

Queues & background processing

Move long-running work out of user requests and manage retries safely.

Observability & diagnostics

Use logs and operational signals to follow a request across services.

A SOLUTION IN CONTEXT

Every channel, one source of truth

A clinic group takes appointments through its website, mobile app and front desk. Each channel keeps its own records, so two patients sometimes book the same slot. A shared API becomes the single source of truth, handles simultaneous requests and tells every channel when the schedule changes.

  1. Receive every request

    Website, app and front desk send bookings to one API

  2. Hold the slot

    Check availability and reserve it, even when requests arrive at once

  3. Sync every channel

    Confirm to the patient and update the schedule for staff

Business value: Patients and staff always see the same schedule.

DELIVERY & QUALITY

Clear deliverables, practical checks

The exact deliverables and acceptance criteria are agreed for your project. These are the foundations we plan around.

What you receive

Services & data model

Backend source code, database changes and business-rule implementation.

API & integration reference

Contracts, authentication requirements and examples for connected teams.

Operational guidance

Failure-handling tests, useful diagnostics and recovery instructions.

How we check it

Predictable contracts

Validate inputs, error responses and compatibility with consumers.

Recoverable integrations

Exercise retries, duplicate events and partial failures.

Visible operations

Make important requests traceable without putting sensitive data in logs.

TECHNOLOGY & INTEGRATION

Built around your ecosystem

These are examples, not a fixed technology list. We choose the approach around your existing systems, operating needs and team.

A FEW MORE DETAILS

Before we get started

Can you integrate with a legacy system?

We review the interfaces, documentation and access available. Where direct integration is limited, we discuss practical alternatives and their constraints before committing to a scope.

How do you handle changing APIs?

We agree compatibility expectations and document contract changes. Depending on the integration, versioning, contract tests and a migration window can help connected teams adapt.

Can you improve performance without replacing everything?

We start with measurement: slow queries, request paths and background work. Improvements are prioritised from evidence and tested against an agreed workload.
