FAQ
How will you access my project or code?
"I am flexible! We can work in two ways: Repository: You can grant me access to your GitHub, GitLab, or Bitbucket repo. Remote Desktop: If you prefer not to share code, we can use AnyDesk or Teamviewer for a live session on your machine."
What information do you need to start fixing the bug?
"To provide a fast solution, I need: 1. A detailed description of the error. 2. The Expected Behavior vs. the Actual Behavior. 3. Any logs, screenshots, or error messages you have encountered."
Is my code and data safe with you?
"Absolutely. I maintain strict confidentiality with every project. Once the bug is fixed and the order is complete, I do not store any sensitive access credentials or private data from your environment."
