Platform Modernisation
Strangle the monolith. Keep the business running.
Many organisations operate legacy systems that limit innovation and agility. We modernise them through architecture redesign, cloud migration, modularisation, and modern engineering practice.
Most large organisations operate legacy systems they are too dependent on to replace wholesale. The big bang rewrite never lands. We use the strangler fig pattern: modular replacement, route by route, with the old system running until the last user is on the new one.
Cloud where it makes sense, on premise where it does not. IaC discipline either way. Architecture you can read, modules you can replace, an operations story your team owns.
The goal is to move faster without rebuilding everything from scratch.
Three ways we modernise.
Stabilise, migrate, and uplift the practice. Most engagements run all three in sequence.

Legacy Rescue
Critical platform diagnostics, architecture redesign, the strangler fig migration plan. We start by stabilising what is hurting and finish with a costed, phased plan you can execute.

Cloud Migration
Lift and reshape, not lift and shift. AWS or GCP, IaC discipline baked in. We migrate piece by piece without downtime and leave you with a deployment story your team owns.

Frequently asked questions
What is the strangler fig pattern?
Modular replacement, route by route, with the old system running until the last user is on the new one. No big bang rewrite. The business keeps moving while the platform changes underneath.
How long does a typical modernisation take?
Months to two years, depending on scope. The first 90 days are a stabilisation and discovery phase that produces a costed plan. After that we move in 6 to 12 week increments.
Do you do greenfield rebuilds?
Only when the legacy is genuinely beyond saving. The default answer is strangler fig. Rebuilds rarely land on time, on budget, or on outcome.
What happens to the team running the legacy?
They move with the work. Modernisation is a capability transfer as much as a code change. We pair with your engineers, run mob sessions, and leave the documentation.
Do you support older stacks?
Yes. We have shipped on .NET, Java EE, COBOL bridges, mainframe-fronting middleware, classic LAMP. Stack age does not scare us.
