FAQ
Can you fix code in other languages?
No. I only work on Node.js with Express. If your project uses something else, message me and I will tell you honestly whether I can help.
What if you cannot find the cause?
Send me the code and the error before ordering. If I look and it is outside what I can fix, I will tell you honestly before you order.
Do you need my passwords or production access?
No. Send the code with secrets removed and use a local or test database. Never share live passwords or keys.
Do you deploy the fix to my server?
No. I deliver the changed code with a written explanation, and you deploy it yourself.
Do you offer calls?
No. I work through written messages only, so everything is documented in the order.
Can you fix it if the bug is in my database queries?
Yes, for MongoDB or PostgreSQL queries used by an Express API. Send the query and the exact error.
