I’m Müller Adolf, a German-based AI developer who helps founders and businesses launch and fix apps built with vibe coding. I work with Lovable, Base44, Replit, Cursor and Claude Code, using Supabase or Firebase for the backend. I fix bugs, clean up AI-generated code, secure apps and take MVPs live. I also build n8n, Make and Zapier automations, AI agents and chatbots. Communication in German or English. Send me your project or broken app and I’ll tell you honestly how fast I can fix it.
FAQ
Which platforms do you work with?
I work with Lovable, Replit, Base44, Cursor and Claude Code projects. If you use another AI builder like Bolt or v0, message me first and I’ll tell you if I can help.
What do I need to send you to get started?
Send your project link or code, a short description of the problem, and any error messages or screenshots. Add what the app should do if it’s not obvious.
How fast can you fix my app?
Simple bugs usually take 1 to 2 days. Bigger backend or cleanup work takes longer. Message me before ordering and I’ll give you an honest time estimate.
Can you fix login and authentication problems?
Yes. I can fix sign-in errors, broken sessions and user roles in apps using Supabase or Firebase authentication.
Do you fix Supabase and Firebase database issues?
Yes. I can fix broken queries, missing data, connection errors and access rules in Supabase and Firebase backends.
Will you explain what went wrong?
Yes. Every fix comes with a short explanation of the cause and what I changed, so you can avoid the same problem next time.
Can you fix errors my AI tool keeps repeating?
Often, yes. I find the root cause in the code instead of re-prompting, so the bug stays fixed. Some issues need a rewrite, and I’ll tell you before starting.
Do you help with deployment and going live?
I can help fix build errors and environment variable problems that block deployment. Tell me where you want to host the app and I’ll confirm what I can do.
Is my code and project kept private?
Yes. I only use your project to complete your order and won’t share or reuse it. If you need an NDA, ask me before ordering.
What if my problem is bigger than the package I picked?
Message me before ordering and I’ll recommend the right package. If the scope grows during the work, I’ll tell you first and offer a custom offer.
