Veelgestelde vragen
My app was built by another developer. Can you still fix it?
Yes. I regularly work with existing codebases, even poorly structured or incomplete ones. I’ll first analyze the code and then fix issues properly without breaking existing functionality.
Can you fix apps built using AI tools like Claude, Codex, or Gemini?
Absolutely. I’ve worked with AI-generated and AI-assisted code. I can clean it up, fix inconsistencies and make it production-ready.
Do you just fix the bug or improve the code as well?
I focus on fixing the root cause. If needed, I also refactor related parts of the code to prevent future issues.
Can you fix urgent or critical issues quickly?
Yes. I offer fast turnaround for urgent bugs depending on complexity. Message me before ordering for priority support.
Will my app be safe and confidential?
Yes. Your code and data are handled securely. I’m happy to sign an NDA if required.
Do you also handle backend or API issues?
Yes. I work with Firebase, Node.js, Express, and databases like MongoDB/MySQL to fix backend-related problems.
Can you continue working on my app after fixing the bug?
Yes. I can provide ongoing maintenance, improvements, or even take over full development if needed.
Will you explain what caused the issue?
Yes. I can provide a clear explanation so you understand what went wrong and how it was fixed.
