AI-driven code migration from legacy app to modern stackMohamed Bouchiba
Stuck with a legacy application that is expensive to maintain and painful to rewrite? I migrate code from one stack to another with AI agents, without a single line written by hand. The agents analyse the old code, rewrite it in the target stack and prove through automated tests that both versions behave the same.
I designed and ran this approach in production for a federal public institution, where it saved over €1M compared with a manual rewrite.
