Solution

Legacy system modernisation 

Move off ageing software without stopping the business that depends on it.

Discuss a projectAsk a question

Older systems often hold years of business knowledge. We help you understand what they really do, plan a safe migration path and replace them incrementally — protecting data and continuity along the way.

What it helps with

  • Reduce dependency on unsupported technology
  • Migrate data safely and verifiably
  • Avoid a risky big-bang switchover
  • Keep what works, improve what doesn't

Examples

The kind of work this covers.

Illustrative examples of the type of work — not descriptions of specific client projects.

  • Incremental replacement

    Replace one capability at a time while the old system keeps running.

  • Data migration

    Plan, test and reconcile data moves with clear sign-off points.

Engagement

How it typically runs.

  1. 01

    Assess the existing system and its users

    Agreed with you at the start, reviewed together as we go.

  2. 02

    Plan the migration path and risks

    Agreed with you at the start, reviewed together as we go.

  3. 03

    Build and migrate in stages

    Agreed with you at the start, reviewed together as we go.

  4. 04

    Decommission safely

    Agreed with you at the start, reviewed together as we go.

How we work

From problem to platform.

The same approach on every engagement. It describes how we work, not a guarantee of particular outcomes or timescales.

  1. 01

    Discover

    We start by understanding the problem, the people affected and the constraints — before proposing anything. Workarounds and spreadsheets are where the real requirements hide.

  2. 02

    Design

    We shape the workflows, data and interfaces with the people who will use them, and agree a first release that delivers value early.

  3. 03

    Build

    We deliver working software in increments you can see, test and steer, with security, accessibility and maintainability built in from the start.

  4. 04

    Integrate

    We connect to the systems you already rely on, with clear ownership of data, monitoring and sensible handling of failures.

  5. 05

    Improve

    Once people depend on it, we measure, support and refine — so the software keeps fitting the way your organisation works.

Technologies we commonly work with: TypeScript, React, Next.js, Node.js, PostgreSQL, REST APIs, Webhooks, Docker, WebGL, Automated testing, CI/CD, Accessibility (WCAG 2.2).

Our standards

Built in, not bolted on.

Every piece of software we build — product or bespoke — is held to the same engineering standards.

  • Secure by design

    Least-privilege access, MFA for administrators, encrypted transport and audit trails — designed in from the first commit.

  • Accessible to everyone

    We build to WCAG 2.2 AA: keyboard and screen-reader friendly, readable contrast and respectful motion.

  • Integration-first

    Clear APIs, signed webhooks and careful data ownership, so new software fits the systems you already have.

  • Observable

    Health checks, error visibility and delivery tracking, so problems are noticed by us before your users.

  • Built to be maintained

    Typed, tested, documented code with migrations and runbooks — software that outlives its first release.

  • Careful with data

    Collect the minimum, keep it only as long as needed, and make access, export and deletion straightforward.
