FAQ
Can you fix any kind of bug?
I handle most backend, API, server, and VoIP-related issues. Contact me first to confirm your specific issue is within my scope.
Do you work on urgent problems?
Yes, I offer fast delivery for critical issues. Reach out and I'll prioritize urgent bugs whenever possible.
What do you need to start?
Access to the code or server and a clear description of the issue (including any error messages and logs if available).
Will you fix the root cause or just patch it?
I focus on proper root-cause fixes for long-term stability, not temporary patches that break again later.
