Sumair Memon
Sobre este Serviço
Is a stubborn bug breaking your MERN stack application? Don't let technical debt or broken code slow down your business.
I am a professional Full-Stack Developer specializing in the MongoDB, Express, React, and Node.js (MERN) ecosystem. Whether its a minor CSS alignment issue or a critical backend logic failure, I provide clean, efficient, and permanent fixes.
What I Can Fix for You:
- Frontend (React): State management errors (Redux/Context API), Hook issues, and UI/UX responsiveness.
- Backend (Node & Express): API endpoint failures, Middleware glitches, and Server-side logic errors.
- Database (MongoDB): Schema validation issues, connection leaks, and CRUD operation failures.
- Authentication: JWT, Firebase, or OAuth login/signup issues.
- Deployment: Fixes for Render, Vercel, Heroku, or AWS hosting errors.
Why Hire Me?
- Root-Cause Resolution: I don't just "hide" the bug; I fix the source code so it doesn't return.
- Clean Code: I follow industry best practices to ensure your code remains scalable.
- Fast Communication: I provide regular updates and a screen-recorded explanation of the fix.
- Post-Fix Support: I offer a 3-day window for any follow-up questions regarding the fix.

Perguntas frequentes
What info do I need to provide to get started?
To fix the bug quickly, I’ll need a brief description of the issue, screenshots or a screen recording (Loom) of the error, and access to your GitHub repository or source code files. If it’s a database issue, I may also need temporary access to your MongoDB cluster.
Can you fix the bug without me sharing my full source code?
n most cases, I need to see the environment where the bug lives to fix it properly. However, for specific logic or UI issues, we can hop on a screen-sharing session, or you can send me the specific code snippets involved.
Do you offer custom offers for large projects?
Absolutely! If your project has multiple bugs or requires a full-scale refactor/feature addition, please message me. I can create a custom quote tailored specifically to your project’s needs and timeline.
Will you explain the fix to me?
Yes! I believe in long-term solutions. Along with the fixed code, I will provide a brief explanation of why the bug occurred and how I resolved it so you can avoid similar issues in the future.
What if the bug returns after the order is completed?
I offer a 3-day post-delivery support period. If the specific bug I fixed reappears within that window, I will jump back in and resolve it at no extra cost to you.
