I debug React, Node.js, Express, MongoDB & Firebase fast without breaking what's working. You get the fix + a 1-line explanation of why it broke.
What I fix:

- MongoDB: connection/query/schema issues
- Deployment: Vercel/Railway/Render env & build failures
- Stripe webhooks, Firebase auth tokens
How it works:
1. Send error + repo access
2. I find root cause
3. Patch, test, deliver clean diff with explanation

Veelgestelde vragen
Do you need access to my code or live website?
Yes, I'll need either a GitHub repository link, a ZIP file of your code, or limited access to your live application (depending on the issue) to diagnose and fix the bug properly.
What if the bug turns out to be bigger than expected?
I'll review the issue first and let you know honestly if it fits your selected package. If it needs more time or a higher package, I'll discuss this with you before starting any work — no surprise charges.
Can you fix bugs in a live/production app without breaking anything?
Yes, I always review the codebase first, test changes carefully, and confirm existing features still work before delivering the fix.
What information should I send when placing an order?
The exact error message, a screenshot if possible, and access to your code (repository or files). The more detail you provide, the faster I can resolve the issue.
What do you need to fix my React/Node bug?
Repo access (GitHub link or ZIP), the exact error message, a screenshot if possible, and steps to reproduce it.
What if you can't fix my MongoDB/API issue?
I'll review it first and tell you honestly if it fits the Basic package. If not fixable in scope, I'll refund or recommend the right package — no surprise charges.
Do you work on live production apps without breaking them?
Yes. I test locally first, send you a clean diff of changes, and confirm existing features still work before delivery.
How fast can you handle an urgent deployment failure?
Under 24 hours for Basic package. Message me first for priority handling on urgent issues.
