FAQ
What happens if you are unable to fix the bug?
As a professional Systems Analyst, technical honesty is my priority. If after the initial assessment I determine the issue requires a different scope or is outside the current tech stack, I will inform you immediately. If I cannot provide a solid solution, I offer a 100% money-back guarantee. Your s
Do you provide documentation with the fix?
Yes. Every delivery (Standard and Premium) includes a brief technical report explaining the root cause of the bug and the steps taken to resolve it. This ensures your code remains maintainable and helps your team avoid similar issues in the future.
Can we discuss the project before I place an order?
Absolutely! In fact, I highly recommend messaging me first. This allows us to align on the technical requirements, check the codebase compatibility (React, Angular, or Node.js), and ensure I can deliver the high-quality results you expect within the timeframe.
What do you need to start?
Access to the code (GitHub/zip) and clear description of the issue.
Do you work on large projects?
Yes, but this gig is focused on small to medium issues.
