You will get React or Next.js bug fixes and performance improvements
Project details
I will investigate and fix reproducible bugs in your React or Next.js application, including runtime errors, state-management issues, broken responsive layouts, API integration problems, loading and error states, and targeted performance bottlenecks.
I follow a structured process: reproduce the issue, identify the root cause, implement a clean fix, and verify that related functionality still works as expected.
You will receive:
• Clean and maintainable source-code changes
• Investigation and root-cause analysis
• Verification of the affected functionality
• A clear summary of the issue and solution
• Responsive or cross-browser checks where relevant
Each package covers the number of related issues and pages or components specified in its scope. Major rewrites, dependency migrations, backend reconstruction, infrastructure failures, security audits, or unrelated additional issues require a custom quote.
Please provide reproducible steps, relevant source-code access, project setup instructions, and screenshots or recordings before the project begins.
