FAQ
What information do you need before starting?
Please provide a brief description of the bug, any error messages/screenshots, and access to your code repository (GitHub/GitLab) or zip file.
Can you sign an NDA or guarantee my code privacy?
Yes, 100%. Your codebase, API credentials, and project data are treated with strict confidentiality and never shared.
Do you test the fix across different devices and browsers?
Yes, every fix undergoes rigorous multi-device and cross-browser testing to ensure zero regressions before delivery.
What if my website or app is experiencing an emergency production outage?
If you are facing a critical live production downtime or crash, please message me directly. I offer high-priority emergency triage to restore server stability and fix the root cause rapidly.
What if the issue reappears after delivery?
Every fix is thoroughly tested before delivery. In the rare event that a related regression or bug reoccurs, I provide dedicated post-delivery support and resolve it immediately at zero extra cost.
