About this gig
Need a bug fixed in your React or Next.js web application?
I will diagnose and fix bugs, errors and small functionality issues in your existing web app.
I can help with:

- API integration issues
- Authentication problems
- Node.js backend issues
- Database-related issues
I work with existing codebases and focus on making targeted, clean fixes without unnecessary changes.
For small, clearly defined issues, you can order the Basic package directly. For larger problems or new features, please contact me first so I can review the scope and recommend the right package.
Tech stack:
Next.js, React, TypeScript, JavaScript, Node.js, Vercel and PostgreSQL.
Please send the error message, expected behaviour and relevant project details before ordering if you are unsure which package you need.
