fix react nextjs frontend and API errors

About this gig

Is a React or Next.js bug blocking your launch or frustrating your users? I will diagnose the root cause and deliver a clean, tested fix.



I can help with:



React component and state errors


Next.js routing, rendering, and hydration issues


API request, response, and authentication errors


TypeScript and JavaScript bugs


Broken forms, validation, and UI interactions


Responsive layout problems


Build and deployment errors


Third-party API integration bugs



You will receive clear communication, focused source-code changes, and testing for the agreed user flow. I will explain what caused the issue and summarize the fix so you can maintain the project confidently.



Please message me before ordering if the problem involves a large legacy codebase, an unfamiliar third-party service, server infrastructure, or several unrelated bugs. Send the error message, reproduction steps, repository access method, and expected behavior for an accurate scope.

I help Web3 teams turn smart-contract functionality into fast, reliable interfaces. With 5+ years of blockchain experience, I build responsive React and Next.js frontends, connect wallets, and integrate contract read and write functions on Ethereum and Polygon. I can help with dApp frontends, MetaMask connections, Web3.js integrations, NFT minting interfaces, DeFi dashboards, and frontend bug fixes. You will receive clean source code, clear communication, and testing for the agreed user flow. Send your design, contract address or ABI, and feature list so I can recommend the right scope.
