Vibe Code Migration

I port your app to a new language and framework and keep the behavior identical. Every screen, rule, and edge case comes across the same way, checked against the original with parity tests so nothing quietly changes.

The new build sits on a language and framework meant to run for years, with typed code, real migrations, a test suite, and a deploy pipeline. It is a base your team can keep extending long after the move is done.

Users, records, and history move over intact. I map the old schema to the new one, migrate the data in stages, and verify row counts and key records on both sides before anything goes live.

I go through the current app and write down what it does: every feature, rule, and integration. That map becomes the checklist the new build has to satisfy.

I pick the target language and framework that fit where the product is going, then lay out the order of work and how the data will move, before writing new code.

I rebuild the app on the new stack feature by feature, checking each one against the original with parity tests. Work ships in pieces so progress stays visible.

I run the new app alongside the old one, move traffic across gradually, and keep the old version ready as a fallback until the new one has proven itself in production.
