FAQ
What do you need from me to start fixing the bug?
Please send a brief description of the issue, a screenshot or copy-paste of the exact console/terminal error log, and access to the relevant code files (or your GitHub repository link)
Is my source code and credential data secure with you?
100%. Security and privacy are my top priorities. I never share your source code, environment variables (.env files), API secret keys, or database credentials with anyone
Do you work with platforms other than React and Node.js?
Yes! While I specialize in the React, Node.js, and Express JavaScript ecosystem, I also comfortably write, optimize, and debug vanilla JavaScript and Python backend scripts.
Can you fix my deployment errors on Vercel or Render?
Yes! If your API works locally but breaks when deployed to a live cloud host, I can analyze your deployment build logs and resolve the host routing or environment variable issues.
