Service
Greenfield specification for new development.
Build the new system on what the old one actually does — not on what people remember it doing. A clean specification, grounded in deterministic facts.
From legacy understanding to a clean spec
We distil the real behaviour of the existing system into a target specification: the business rules worth keeping, the interfaces that must be preserved, and the risks to design out.
What you get
Target architecture input
A specification a modern team — or an agentic pipeline — can build against with confidence.
Preserved behaviour
The rules and interfaces that must survive the rewrite, captured and cited.
Designed-out risk
The hidden dependencies and dead code identified, so they don’t carry forward.
