Service / Engineering / 04
We replatform, refactor or rebuild legacy estates with a clear value-case—cost out, velocity up, risk down. Strangler-fig patterns, contract-first APIs, and a relentless focus on production reality.
01 — Service Overview
We've seen too many big-bang re-platforms that take three years and ship nothing. Our approach is incremental, instrumented, and tightly bound to the P&L impact you signed up for.
Whether you're unwinding a mainframe, splitting a monolith, or rationalising a portfolio of 400 apps—we sequence the work so that every step pays for the next.

02 — Challenges We Solve
Critical workloads trapped on platforms no one wants to touch—and no one knows fully anymore.
Hundreds of overlapping apps, each with its own roadmap, vendor and tax on the operating model.
Unsupported runtimes, expiring licences, security gaps—the cost of inaction is rising every quarter.
Quarterly deploys, weeks of UAT, fear-driven change advisory boards. Innovation has nowhere to land.
03 — What We Deliver
Tangible deliverables, not motherhood statements. Pick the ones that matter, ignore the rest.
Quantified portfolio-level view: what to retire, refactor, replatform or rebuild.
Incremental decomposition that ships value every quarter, not every three years.
Pragmatic migration patterns from COBOL, AS/400, Oracle EBS, SAP ECC and more.
Re-host, re-platform or re-architect—chosen per-app on a clear ROI lens.
Contract-first APIs and event meshes that decouple your roadmap from your past.
Team topologies, governance and engineering practices to sustain the gains.
04 — How We Work
01
Senior partners lead a focused discovery sprint to anchor the work in your value case.
02
A target architecture pressure-tested against your data, regulators and operating model.
03
Lean senior squads ship to production in short, instrumented increments tied to outcomes.
04
We run alongside your team, then hand over a self-sufficient internal capability.
05 — Use Cases

07 — Why partner with us
No pitch teams, no graduates running production. The people you meet are the people who deliver.
We close the gap between the boardroom recommendation and the system in production.
We put a meaningful share of fees at risk against the value case we sign together.
Our success criteria includes leaving a self-sufficient internal team behind.
