Step 3

Automate tests so each change is safe to ship.

Frequently asked questions

Can you modernise without stopping the business?

Yes. We use strangler patterns: new modules ship alongside legacy code, automated tests protect existing behaviour, and cutover happens in phases when each slice is proven stable.

What does a legacy audit cover?

Code quality, security risks, deployment pain, data model debt, and integration dependencies. You get a prioritised roadmap with cost and risk for each modernisation slice.

How many sprints does modernisation usually take?

Three build sprints cover most focused modernisation projects after discovery. Larger rewrites are split into multiple phases so you can pause between milestones.

Will our team be able to maintain the new system?

Handover includes architecture docs, runbooks, and pairing sessions. We write code your team can own - clear boundaries, tests on critical paths, and no magic frameworks.
