I will fix bugs and errors in your react, node js, and mern app
Abdul W
Over deze dienst
Is a stubborn bug breaking your MERN stack application and costing you users?
Stop pulling your hair out over a blank white screen, a failed API request, or a MongoDB connection timeout. I am a full-stack MERN developer, and I specialize in diving into existing codebases to find and squash bugs fast.
Whether it is a minor UI glitch in React or a critical backend failure in Node.js, I will identify the root cause and provide a clean, permanent solutionnot just a temporary patch.
I can help you fix:
- React Issues: Broken hooks (useEffect/useState loops), component rendering errors, Redux/Context API state bugs, and routing failures.
- Node.js & Express: Crashed servers, middleware failures, CORS errors, and broken REST API endpoints.
- MongoDB/Mongoose: Schema validation errors, slow queries, and database connection timeouts.
- Frontend UI: CSS/Tailwind/Material UI responsiveness issues across mobile and desktop.
Why hire me?
- I read and understand existing code quickly.
- I will explain exactly what broke and how I fixed it so it doesn't happen again.
- Fast turnaround timesbecause broken apps lose money.
️ IMPORTANT: Please message me with a description of the bug and a screenshot of the error

Veelgestelde vragen
What information do you need to start fixing the bug?
Please provide a detailed description of the bug, steps to reproduce it, and access to your source code. You can invite me to your GitHub/GitLab repository or provide a ZIP file containing the code and any .env structure needed to run it locally.
Do you work on live production servers, or do you need a staging environment?
For your security, I highly prefer testing and fixing bugs locally or on a staging branch. Once the bug is fixed and tested, I will send you the updated code or push it to a branch for you to review and merge into production.
What happens if you cannot fix the bug?
I will review your codebase and the issue before we start the order. If I find that the bug is outside my scope or cannot be fixed due to third-party library limitations, I will let you know upfront so you do not waste your money and specially your time.
Do you fix bugs in other frameworks like Angular or Vue?
No, I specialize exclusively in the MERN stack (MongoDB, Express.js, React, Node.js) & Next.js. In these technologies, I can guarantee faster, higher-quality debugging for my clients. But as a dev, I will review your problem first, & if a bug in Vue or Angular can be fixed, I will surely help you.
Can you fix my UI/CSS responsiveness issues on mobile?
Yes! Whether it is a broken flexbox, Tailwind CSS issue, Material UI component glitch, or standard CSS media queries acting up on mobile devices, I can fix frontend design bugs as well as backend logic errors.
