API & Microservices Architecture

Design APIs and service boundaries that help applications exchange data and responsibilities reliably. Make integration behaviour explicit before systems become tightly coupled.

Software Development / Specialist service

Connect systems with clear contracts.

Design APIs and service boundaries that help applications exchange data and responsibilities reliably. Make integration behaviour explicit before systems become tightly coupled.

Discuss your project

01 / Define useful contracts

Define useful contracts

Document resources, request and response structures, authentication, error behaviour, and versioning for the teams consuming each API.

02 / Choose boundaries carefully

Choose boundaries carefully

Separate services around ownership and operational needs. Review data consistency and communication patterns before adding distributed components.

03 / Operate the integration layer

Operate the integration layer

Plan tracing, rate limits, monitoring, and compatibility checks. Make changes and failures understandable across teams.

04 / Your project

Talk through your use case

Discuss api & microservices architecture in the context of your current systems, your team, and the outcome you need. Define a focused starting point before implementation.

Talk to DEQX

Clarity before commitment.

Shape the engagement around the work you need. Specific deliverables, access, responsibilities, and acceptance criteria are agreed during discovery.

What we start with

  • User journeys and business priorities
  • Existing architecture and integrations
  • Release and support expectations

What the scope can cover

  • Define useful contracts
  • Choose boundaries carefully
  • Operate the integration layer

What we agree together

  • A defined scope and prioritized delivery plan
  • Review points and acceptance criteria
  • Documentation and ongoing ownership

A practical path from idea to operation.

A staged approach gives your team clear review points. Timing and responsibilities depend on the scope and the readiness of the systems involved.

  1. 01

    Understand the workflow

    Map user journeys, requirements, existing systems, and acceptance criteria with the people responsible for the work.

  2. 02

    Design and validate

    Review the interface and architecture early. Resolve integration and data decisions before they become costly to change.

  3. 03

    Build in reviewable increments

    Implement and test agreed priorities, with regular demonstrations and a clear process for handling scope changes.

  4. 04

    Release and hand over

    Prepare deployment, documentation, support ownership, and the next development priorities.

Before we begin

Useful answers. Clear expectations.

A few questions to help frame your api & microservices architecture project.

Can existing APIs be improved without breaking consumers?

A compatibility review identifies dependent clients and current behaviour. Versioning, staged rollout, and deprecation plans can support changes while consumers migrate.

How is the scope and delivery plan defined?

We begin with your current situation and the outcome you need. For this service, the discussion covers define useful contracts, choose boundaries carefully, operate the integration layer. Deliverables, dependencies, review points, and commercial terms are agreed before implementation.

What happens after the initial delivery?

Handover, maintenance, and ongoing improvement are discussed as part of the engagement. The arrangement depends on your internal team, the systems involved, and the operating responsibilities you want DEQX to support.
