Integration and modernisation
Change long-lived systems without losing what already works.
Older software often contains years of business knowledge. We find that knowledge, improve the parts creating risk and connect the system to new applications and services.
Integration
Connections that behave predictably.
APIs
We define interfaces, ownership, versioning and error behaviour so connected systems can change independently.
Messages and workflows
Many systems exchange updates through messages as changes happen. We design those integrations to handle duplicates, retries, delays and partial failures.
Identity and access
Permissions are made explicit across applications and data sources.
Data access
Existing data becomes available to new services without creating another uncontrolled copy.
Modernisation
Improvement in manageable stages.
Understand the current system
We inspect the code, data model, interfaces and operational history before recommending change.
Find the important rules
Business behaviour that must be preserved is separated from implementation choices that can be replaced.
Change in stages
Small, reversible changes come before a full rewrite, unless the evidence supports a replacement.
Keep the team involved
We document decisions with the engineers who will maintain the system, so they understand both the design and its trade-offs.
Which part of the system is getting in the way?
Describe the interfaces, the data and the change you need to make. A principal engineer will reply.
