FAQ
Can you work on a project built by someone else?
Yes. I'm comfortable jumping into existing codebases. Share your code via GitHub or as a zip file and I'll review it before we begin.
How do I share my project with you?
You can share it via a GitHub repository link or as a zip file through Fiverr. For sensitive projects, I treat all code and business information with complete confidentiality.
How will you fix my bug if you don't know my full codebase?
I'll start by reviewing the relevant parts of your code, reproduce the issue on my end, identify the root cause, and fix it properly — not just patch it on the surface.
Will my existing code and features be affected by your changes?
I'm careful to make targeted changes only where needed. I won't restructure or rewrite parts of your app that aren't related to the task — your existing functionality stays intact.
Are the prices fixed or do they depend on the task?
Pricing depends on the complexity of the task. Message me with your requirements and I'll give you an accurate custom quote.
