I will need a description of the bug/feature, access to your codebase (via GitHub, Zip file, or screen share), and any specific error logs or screenshots.
What if you are unable to fix my issue?
If I cannot resolve your bug or fulfill the agreed scope, you will receive a full refund. No risk involved!
