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.
