I will fix bugs in react node js express and mern apps
M Ahmad Usman
About this gig
Are bugs slowing down your React or Node.js application? Lets get it fixed.
When your MERN stack app breaks, you need someone who understands how the frontend and backend talk to each other. Having independently developed and architected full-stack applications with complex Node.js backends and React-based frontends, I know exactly where bugs like to hide.
I don't just apply temporary patches; I analyze the root cause so the issue doesn't come back, ensuring my fixes maintain the integrity of your codebase.
What I can fix for you:
- React.js: State management issues, rendering errors, component lifecycle bugs, and responsive UI fixes.
- Node.js & Express: API routing errors, server crashes, middleware bugs, and asynchronous logic issues.
- MongoDB: Database connection errors, slow queries, and schema model fixes.
- Integration: Issues fetching data from your API to your frontend.
Why work with me?
- Clean, well-documented code.
- Seamless collaboration via Git/GitHub.
- Fast communication and reliable delivery.
Important: Please send me a message with a brief description of your bug before placing an order so I can make sure we pick the right package!

FAQ
How do I share my code with you?
The best way is to invite me to your GitHub repository. Alternatively, you can send a zipped folder of your source code, but please remember to exclude the node_modules folder!
What if I am not sure which package to choose?
No problem at all! Just send me a message with a screenshot or description of the error you are facing. I will review it and recommend the right package, or create a custom offer for you.
Do you fix bugs on live/production servers?
To ensure your users aren't affected, I prefer to troubleshoot and fix bugs in a local or staging environment. Once the fix is verified, you can safely deploy it to your live application.
