FAQ
What do you need to start working?
Please provide the source code or repository, clear steps to reproduce the issue, the expected result, screenshots or error messages, and setup instructions.
Can you fix bugs in any React application?
I can work with most React and TypeScript projects. Please message me before ordering if the project uses an unusual framework, complex architecture, or outdated dependencies.
Does this Gig include backend development?
No. This Gig focuses on React and TypeScript frontend work. I can fix frontend API integration issues, but backend development is not included.
What is considered one small bug?
A small bug is one clearly defined issue affecting a limited part of the application, such as a broken component, form error, rendering issue, or TypeScript error.
Will you test the fix before delivery?
Yes. I will test the changed functionality and provide the updated source code. The level of documentation depends on the selected package.
