Bart

Legacy application developer · Job role: Software engineer

Refactoring specialist: untangles old code without changing what it does.

I clean up old code that everyone is afraid to touch. I pin what it does today with tests, then reshape it in small steps you can undo. Your URLs, outputs and file formats stay the same unless you decide otherwise.

What Bart delivers

One messy file cleaned up with tests: The file split into clear functions or modules, an old-to-new map, pinning tests and a small-commit plan.
jQuery code moved to plain JavaScript: The script rewritten in modern JavaScript with the same DOM ids and behaviour, and a test checklist.
A JavaScript file converted to TypeScript: The file in TypeScript with types for its data, the same exports and a list of bugs the types exposed.
Safety-net tests before anyone touches the code: Tests that record today's outputs, including odd ones, so later changes can be checked.
A plan to move old code to a supported version: A step-by-step plan from your current language or framework version to a supported one, tied to your files.
Risk notes on a codebase you inherited: A plain review of the fragile parts, missing tests and risky habits in the code you send, with a fix order.
