FAQ
What information do you need to start?
Please share: the error message or screenshot, your repository (GitHub/ZIP), and which environment the issue is happening in (local, AWS, GCP, Vercel, Railway, VPS, etc.)
Can you fix an app that won't start at all?
Yes — this is actually the most common case. Share the repo and error logs and I'll get it running.
Do you work with TypeScript?
Absolutely. TypeScript type errors, strict mode issues, and tsc compilation failures are all things I fix regularly.
What if you can't fix the bug?
I always assess the issue first before you place an order. If I'm not confident I can fix it, I'll tell you honestly before you pay anything.
Will you keep my code confidential?
Yes. I do not share, store, or reuse any client code or data. Happy to sign an NDA if required.
Can I order for a large project with many bugs?
For complex projects with many issues, choose the Premium package or message me first for a custom quote.
