Perguntas frequentes
What do you need from me to start debugging the issue?
To fix the bug efficiently, I will need a clear description of the error, any relevant error logs or browser console screenshots, and access to your code repository (such as GitHub or GitLab). If it is a deployment issue, temporary hosting or server access will be required.
Do you fix issues on WordPress, Shopify, or other CMS platforms?
No, I do not work with pre-built CMS platforms. My services are strictly focused on custom-coded full-stack applications built with modern frameworks like React, Next.js, Node.js, and Express. I favor high-quality, custom development solutions over template-based platforms.
Will my source code and database information remain secure?
Absolutely. Your intellectual property, database credentials, and source code are treated with the highest level of confidentiality. Once the debugging process is completed and verified, all local copies of your data and credentials will be securely wiped from my system.
What happens if the same bug returns after deployment?
I prioritize quality over speed by refactoring the faulty code logic permanently rather than using a temporary patch. However, if the exact same issue resurfaces within the scope of my fix, simply reach out to me and I will resolve it immediately at no additional cost.
Can you troubleshoot cloud deployment and server errors?
Yes. In addition to frontend and backend code logic, I can debug cloud-related issues, including broken AWS configurations, Docker container deployment crashes, environment variable conflicts, and Nginx reverse proxy faults.
