I have an existing React.js site that has begun throwing errors and behaving unpredictably. I need a developer who can clone the repository, run the project locally, isolate the root causes, and commit clean, tested fixes back to the main branch. The brief is broad on purpose—I want a full sweep rather than a quick patch in one spot. Your work will include tracing runtime warnings, updating any outdated dependencies, tightening state management, and confirming that the final build renders correctly in current versions of all major browsers. Please keep your commits well-commented and maintain a short log outlining each issue you uncover and how you solved it. Deliverables • Updated codebase pushed to the repo • One-page report summarising identified issues and applied fixes • Recommendations for any follow-up improvements A staging sub-domain is ready for deployment tests, and I’d like to review an initial round of fixes within 48 hours. When you reply, let me know your availability and point me to a couple of relevant React troubleshooting projects you’ve handled before.

Hello , I’m available to start immediately and can deliver an initial round of fixes within 48 hours as requested. I work primarily with React (functional components + hooks), modern JavaScript/TypeScript, and structured state management patterns. I’ve handled several troubleshooting cases where applications were throwing runtime warnings, dependency conflicts, hydration issues, and inconsistent rendering across browsers. Here’s how I would approach your project: Clone and run the repository locally to reproduce all errors and warnings. Trace runtime issues using browser dev tools and React DevTools. Audit and safely update outdated dependencies while preventing breaking changes. Review state management patterns to eliminate unnecessary re-renders, race conditions, or improper side effects. Test the final build across major browsers to confirm stability. Push clean, well-commented commits and provide a concise one-page issue report outlining: Root cause Fix applied Preventive recommendations I follow clean Git practices and structured debugging so fixes are stable—not temporary patches. Availability: I can dedicate the next 2–3 days fully to this project. I’d be happy to discuss repository access and get started right away. Best regards, Shahzeb
