Custom application development and modernization.

We build the new systems a business needs and refactor the older ones holding it back. Software shaped around how you actually work, designed to be cheap to run and easy to change.

Overview

What it is

Off-the-shelf does not always fit, and old systems can quietly tax everything around them. We build custom software shaped around how you actually work, and we modernize legacy systems without a risky big-bang rewrite. Security and operability are designed in, so what we ship is cheap to run and easy to change.

Outcomes

Software that fits the work instead of fighting it
Lower run cost and faster, safer changes
Older systems modernized without a risky big-bang rewrite

What is included

The sub-services in the Software practice.

Custom application development

New systems built around your business, not the other way round.

Modernization and refactoring

Untangle legacy systems safely, one well-tested piece at a time.

APIs and integration

Make your systems talk to each other cleanly and reliably.

Cloud-native engineering

Services, containers, and sensible automation that scale with demand.

Platform and developer experience

Pipelines and tooling so your teams ship safely and often.

Quality and testing

Automated testing and review built in, so changes are boring in the best way.

Our approach

How we deliver.

01
Understand the work the software has to support.
02
Design for change, security, and a low run cost.
03
Build and ship in small, safe increments.
04
Operate and evolve, so it keeps fitting as you grow.

Surviving a 3.4x peak on a re-architected storefront, then spending less off-peak

Questions

About the Software practice.

Can you modernize without a full rewrite?

Almost always. We use a strangler-fig approach to replace risky parts piece by piece, so the business keeps running throughout.

Will you work with our existing engineers?

Yes. We work alongside your team and leave them able to own and extend what we build.

Who owns the code?

You do. We build in your repositories, document as we go, and hand over cleanly.

The rest of the estate

Stronger together than apart.

01 / CLOUD

Migration, operations, and cost control across any platform.

02 / DATA

Platforms, pipelines, analytics, and governance.

03 / AI

Practical AI and machine learning, pointed at real outcomes.

04 / SECURITY

Cybersecurity, identity, compliance, and audit readiness.
