I will be you bug fixing expert

Acerca de este Servicio
Is your MERN stack app broken, crashing, or behaving unexpectedly? You're in the right place.
With 4+ years of hands-on experience in MongoDB, Express.js, React, and Node.js, I specialize in diagnosing and fixing bugs that slow down your product and frustrate your users.
WHAT I CAN FIX:
React component errors, state/props issues, broken UI
Node.js/Express API errors, crashes, and failed routes
MongoDB query issues, schema errors, data not saving
JWT authentication & session bugs
CORS errors and middleware issues
Console errors, warnings, and silent failures
Deployment bugs (Heroku, Vercel, Render, VPS)
Performance issues and memory leaks
HOW IT WORKS:
1. Share your code (GitHub, ZIP, or direct access)
2. Describe the bug or paste the error
3. I'll investigate, fix, and explain what was wrong
I work with startups, agencies, and solo developers who need fast, reliable fixes without the back-and-forth.
All fixes come with a clear explanation so you understand what changed and why.
Message me before ordering if you're unsure I'll tell you honestly if I can help.

FAQ
Q1: How do I get started?
A: Simply place your order and fill out the requirement form. Share your GitHub repo link or a ZIP of your code along with a description of the bug. The sooner you share details, the faster I can start.
Q2: What if you can't fix the bug?
A: If after a thorough investigation I genuinely can't fix it, I'll let you know honestly and offer a full refund. I won't waste your time — I'll always tell you upfront if a bug is outside my scope.
Q3: Do you need full access to my project?
A: I only need access to the relevant files or the full repo if needed. You can share a private GitHub repo, send a ZIP, or use a private link. I handle all code with strict confidentiality.
Q4: Will you explain what the bug was and how you fixed it?
A: Yes, always. Every fix comes with a clear explanation of what caused the bug and what I changed. You'll understand the solution, not just receive a black-box fix.
Q5: Can you fix bugs in code you didn't write?
A: Absolutely. Most of my clients share inherited or third-party codebases. I'm experienced in reading and debugging unfamiliar code quickly.
Q6: What if there are more bugs than the package covers?
A: Message me before or during the order. I'll either suggest an upgrade to a higher package or create a custom offer based on the scope.
