React and Node.js Developer Needed to Fix API/Data Sync Issue

I'm running into an issue in my existing React + Node.js application and need someone who can jump in today. We have a customer list page built in React. When a user edits a customer's information and clicks Save, the API returns a successful response and the database is updated correctly, but the UI continues showing the old data until the page is manually refreshed. I also noticed that one of our Node.js/Express endpoints occasionally returns stale data, so I'm not sure whether the issue is on the frontend, backend, or both. I'm looking for someone to: • Investigate the root cause • Fix the React state/data refresh issue • Review the Node.js API endpoint and update it if needed • Test everything before wrapping up The project is already running locally, and I'll share the Git repository once we connect. This should only take 1 to 2 hours for someone experienced with React and Node.js. Requirements: • Strong experience with React.js • Node.js / Express • Experience debugging React state management and API-related issues • Able to start immediately If you're available now, please reach out ASAP and share relevant experience of projects with similar fixes.
