FAQ
What information do you need to start?
Please provide a description of the issue, screenshots, error messages, and steps to reproduce the problem. Source code access may be required.
Can you fix any React or NextJS bug?
I can fix many common frontend issues. Complex bugs, major architectural changes, and new features require a separate assessment.
Will you make changes directly to my live website?
I prefer to test fixes in a development or staging environment before applying changes to production. Production deployment must be agreed upon in advance.
What is included in a revision?
A revision includes adjustments related to the originally agreed bug fix. Additional features or unrelated issues are not included.
