Facing bugs or errors in your MERN stack application?
I'm here to help you quickly troubleshoot, debug, and fix issues so your app runs smoothly again.

What I can fix:
- React.js issues (component errors, hooks, state management, routing, UI glitches)
- Node.js / Express backend problems (API errors, crashes, authentication issues)
- MongoDB connection, schema, and query errors
- Performance bottlenecks and optimization
- Real-time feature bugs with WebSockets
- AI integration issues and custom MCP server problems
- Backend fixes using Python & Django (if your project mixes technologies)

FAQ
What specific technical issues can you resolve ?
I specialize in troubleshooting the entire MERN stack and Python/Django environments. This includes fixing React hook/state errors, broken Express APIs, MongoDB schema conflicts, and WebSocket connectivity issues. I also handle advanced debugging for AI integrations and custom MCP servers.
I’m ready to start! What do you need from me?
To begin, I’ll need a brief description of the bug and, if possible, screenshots or error logs. Once we chat, I’ll need access to your repository (GitHub/GitLab) or the specific source files. I’ll guide you through the process to ensure a smooth handoff.
Can you handle urgent, "site-down" emergencies?
Yes. I understand that downtime costs money. I prioritize critical fixes that stop your business from functioning. Please message me immediately with the subject "URGENT" so I can evaluate the fix and provide an accelerated timeline.
What is your policy on revisions?
Your satisfaction is my priority. I provide support until the specific bug we agreed upon is 100% resolved. If the fix doesn’t work in your production environment as it did in staging, I will stay on it until it’s perfect.
How do you ensure my code and data stay secure?
I treat your intellectual property with total confidentiality. I prefer working on local clones of your repo, and I never share your code with third parties. Once the project is signed off, I purge your sensitive data from my local environment.
Can you make my slow application faster?
Absolutely. Beyond just "fixing" errors, I offer performance optimization. I can audit your React rendering, optimize MongoDB queries, and streamline Node.js middleware to ensure your app is lightning-fast and scalable.
Do you build full applications from scratch?
Yes! While this Gig focuses on debugging, I am a Full Stack Developer. I can build complete, future-ready products—from MERN-based SaaS platforms to AI-powered web apps. Check my other Gigs or message me for a custom project quote.
Is it safe for you to work on my live production site?
I follow industry best practices: I typically debug in a local or staging environment first to ensure the fix is stable. Once verified, I can help you deploy the fix to your live server (AWS, Vercel, Render, etc.) safely without disrupting your users.
What if my issue is more complex than the package I bought?
No problem! If the scope of the bug is larger than anticipated, I will stop and explain the situation clearly. We can then adjust the order or I can send a Custom Offer that covers the additional complexity, so there are never any surprises.
