FAQ
What do I need to provide before you start?
Please provide a brief description of the bug, the expected behavior, error logs, and access to the relevant part of your Golang source code.
What if my bug is highly complex or takes more than an hour to fix?
If the issue requires a deep architectural rewrite or extensive troubleshooting, please message me first. I will analyze the problem and send you a custom offer tailored to the complexity.
