I will fix react next js node js and mern stack bugs and errors


About this gig
Are React, Next.js, Node.js, or MERN stack bugs slowing down your web application?
I will debug and fix frontend, backend, API, database, authentication, responsive design, and deployment issues in your existing application. I can resolve React component errors, Next.js routing or hydration problems, Redux state issues, REST API failures, Express server bugs, MongoDB/Mongoose errors, CORS problems, cookie and JWT authentication issues, Cloudinary uploads, and Vercel deployment errors.
You will receive clean, reliable fixes that preserve your existing functionality and design. I will carefully inspect the issue, identify the root cause, implement the solution, test the affected flow, and explain what was fixed.
My core stack includes React.js, Next.js, Tailwind CSS, Redux Toolkit, Node.js, Express.js, MongoDB, REST APIs, Cloudinary, and Vercel.
Contact me before ordering with the error details and project scope so I can recommend the correct package. Large features, complete redesigns, and rebuilding projects require a custom offer.
