A modernization service, not a tool. Four gated stages, fixed price each.

How an engagement runs

What we deliver

Three engagements.
One operating model.

Scoped, staged, and delivered with evidence at every step. Pick the one that matches the problem in front of you — each starts with the same Assessment.

01 · API-first architecture

Business logic does not stay
where you put it

The same rule gets written twice, drifts twice and gets fixed twice — assuming anyone remembers both places.

01

Logic duplicated front and back

One rule, two implementations, two drift paths. Fixing one is the bug that comes back.

02

Every change touches everything

With no clean boundary, a small product update becomes a change request across three teams.

03

No single source of truth

When the same rule lives in three services and a component, nobody can say which is correct.

04

In-house attempts stall

The extraction starts, hits the first undocumented dependency, and leaves the roadmap.

02 · Agentic context layer

Your AI tools are only
as good as what they know.

Rolling out every agentic tool on the market will not move the needle if the bottleneck is context rather than tooling. We build the knowledge base, validate it with your engineers, and hand it over.

It is not documentation. Documentation is prose, and prose goes stale the week it is written. This is extracted rules, flows and system behaviour, structured so an agent can act on it — and exposed over MCP so every tool reads the same validated source.

  • Copilot, Cursor, Claude Code and your own MCP servers, one source
  • Rules and critical flows extracted, then validated by people
  • Refreshed as the codebase moves, not frozen at hand-off

03 · Large-scale migrations

Taken on directly, not advised on

Complex migrations with a fixed scope, staged delivery and validation at every step. The work is ours; the system stays yours.

01

.NET migration

Framework to modern .NET, with parity tests proving the behaviour did not move.

02

Java migration

Version and platform moves across services that were never meant to be separated.

03

Monolith to microservices

Boundaries drawn from the dependency map rather than from the org chart.

04

Mainframe modernization

COBOL, JCL and PL/I read, mapped and documented before anything is rewritten.

05

AI-ready codebase

The same analysis, aimed at making the system legible to agents rather than moving it.

06

M&A technical due diligence

What you are buying, mapped: architecture, dependencies, dead code, real risk.

In their words

What the engineers said afterwards

They handed us a map of the application and our own analysts checked it line by line. It held up. Every detail the business side had been asking for was in there.

Questions

About the engagements

No. Everything is delivered through a live customer workspace. The deliverable is the architecture change itself, not a tool your team has to learn and keep running.
Anything that speaks MCP — Copilot, Cursor, Claude Code, your internal agents and your own MCP servers. The layer is built to be queried rather than read.
Documentation describes the system in prose and drifts the moment the code moves. The context layer is extracted structure — rules, flows and behaviour — validated and queryable, and Enablement hands over what your team needs to keep it current.
Usually that is the right move. Assessment is scoped to the smallest piece of the estate that will produce real evidence, and it stands on its own if you decide to stop there.

Start with one codebase

Pick the engagement that produces evidence soonest

Bring the repository you are most worried about. That is usually the right place to start.
