Third-Party System Integrations
We help businesses connect applications, services, and data workflows to reduce manual effort and improve information flow.
Services
Backend Architecture & API Engineering
We build the server-side foundations that enable applications to process information, enforce business rules, and communicate reliably with other systems.
What’s included
What this service covers
The main capabilities within backend architecture & api engineering. The scope of each project is agreed with you during discovery.
-
Backend system design
Structuring services, data flow and responsibilities so the system stays understandable and maintainable.
-
REST API development and integration
APIs that let your applications and partner systems exchange data in a consistent, well-defined way.
-
Database architecture and data modelling
Data structures designed around your business entities and the questions you need to answer.
-
Authentication and authorization workflows
Sign-in and permission checks enforced on the server, not only in the interface.
-
Business logic and data processing
Business rules implemented in one dependable place, so every application behaves the same way.
-
Scheduled tasks and background processing
Jobs that run on a schedule or outside the main request, where the project requires them.
How we approach it
Practical engineering, shaped around you
We aim to understand the business problem first, then choose a solution that suits it and can be maintained.
- Several applications need to share the same data and rules
- An existing backend is hard to change or extend
- Partners or other systems need an API to connect to yours
- Processing has to run in the background or on a schedule
- 01
Define the contract first
We agree how systems will communicate before building: endpoints, data formats and how errors are handled.
- 02
Design for maintainability
We consider performance, maintainability and scalability from the design stage, in proportion to the needs of the project.
- 03
Keep rules in one place
Business logic lives in the backend, so web, mobile and partner integrations all follow the same rules.
How we deliver
From first conversation to handover
We follow a structured development approach intended to keep project objectives, implementation, and delivery expectations aligned.
- 01
Discovery & Requirements
We understand the business problem, intended users, existing systems, operational workflows, and desired outcomes.
- 02
Solution Architecture & Planning
We define the proposed scope, key components, integration requirements, milestones, dependencies, and acceptance criteria.
- 03
Design & Engineering
We develop the application, backend services, integrations, and business logic according to the agreed requirements.
- 04
Validation & Quality Assurance
We test implemented functionality, review integrations, resolve identified issues, and validate requirements against agreed acceptance criteria.
- 05
Deployment & Handover
We coordinate deployment and provide the agreed deliverables and handover information.
- 06
Maintenance & Evolution
Where included in the engagement, we support ongoing maintenance, issue resolution, and future improvements.
Questions
Common questions
What is backend and API engineering?
It is the server-side work that lets applications store data, apply business rules and exchange information with other systems, usually through APIs.
Can you build an API for an existing application?
Yes. REST APIs can be developed for new or existing applications, and we also integrate with APIs provided by other systems.
Can you improve a backend that already exists?
Troubleshooting, performance improvements and improving legacy workflows are part of our ongoing engineering work. What is practical depends on the system, which we assess during discovery.
