FAQ
What types of backend bugs can you fix?
I fix bugs in Node.js, Express.js, FastAPI, Django, and Python backends — including API errors, broken endpoints, database issues (MongoDB, PostgreSQL, MySQL), authentication bugs, logic errors, and slow API performance.
Can you fix my bug if I'm not sure what's causing it?
Yes. Message me with your error message, logs, or a brief description of what's broken. I'll review it, identify the likely cause, and confirm I can fix it before you order. No obligation to buy.
What if the bug isn't fixed within 24 hours?
I'll communicate immediately if anything changes. I won't close an order without delivering a working fix or a full explanation. Your satisfaction and on-time delivery are my priority on every order.
What do you need from me to get started?
Share your error message or logs, a short description of what's broken, and access to the relevant code via GitHub or a zip file. The more context you give, the faster I can deliver the fix.
