App rescue & codebase stabilisation
Your app was built by another team, a freelancer who disappeared, or an AI tool, and now it crashes, builds fail or every change breaks something else. We audit it, fix what is critical, and make it safe to keep building without a rewrite unless one is truly needed.

Questions
Do you have to rewrite my app?
Usually not. Clients often need fixes while staying fully within the existing stack, and that is how we work by default.
Can you fix an app built with AI coding tools?
Yes. We read the generated code like any other codebase, remove the parts that cause instability, and add structure so it can grow.
How do we start?
Share access to the repository and crash logs. We start with an audit and a prioritised list before any larger work.
