Migrate off the system nobody can describe.

Design partners

Most enterprise transformation is cosmetic: a new interface wrapped around forty-year-old behaviour. Code Doctor is for the other kind — it maps the estate, recovers the intent nobody wrote down, and hands you a rulebook the next migration starts from.

codedoctor.ai

The Code Doctor pipeline: topology discovery, pattern extraction, intent validation, rulebook, parallel-run verification.

codedoctor.ai — the pipeline, from estate to proven cutover.

Why it exists.

Every modernisation we were brought into stalled in the same place: nobody could describe the system being replaced. Not the vendor, not the incumbent team, not the documentation. So the first thing we built was the thing that reads what is already there.

What it does.

Estate topologyRepositories, services, routes, jobs and the integrations between them, mapped across the estate rather than sampled from one repo.

Deterministic extractionFacts lifted at machine scale from Java and Spring, .NET, Python and TypeScript — each one carrying the source location it came from.

Database logicPostgres and SQL Server introspection: stored procedures, triggers, functions and scheduled jobs. The decisions source-only tools never see.

Intent validationA structured flow that puts open questions in front of the engineers who still know, and records the answer against the fact it explains.

The rulebookA machine-readable description of the system, owned by you, versioned like code, and reusable by the next migration.

Equivalence before cutoverThe generated system is measured against the original rather than declared finished. Demonstrated end to end on a reference pair.

Who it is for.

Regulated and public-sector estates where the system cannot be switched off, the behaviour cannot be guessed at, and the auditors will ask how you knew.

Status and access.

Onboarding a small number of design partners. An assessment is the first step and the output is yours regardless of what follows.
