Bug Fixing for Laundry Management System

I am looking for an experienced MERN stack developer to identify and fix bugs in an existing Laundry Management System web application. The system was working properly before a recent UI/design update, after which multiple features became unstable or stopped working. This is a live project and does not require building anything from scratch.

- Debug issues introduced after the recent design/UI changes
- Fix broken functionality across the application
- Ensure proper integration between frontend (React) and backend (Node.js/Express)
- Validate API calls and data flow between frontend and MongoDB
- Restore overall system stability and performance
- Perform basic testing to confirm fixes

Required: React.js, Node.js, Express.js, MongoDB

- Proven ability to debug and fix existing production code
- Understanding of frontend–backend integration issues
- Ability to deliver within a tight timeline
- Clear and professional communication

Deliverables:
- All reported bugs resolved
- Application functioning as expected after UI update
- Tested and stable system

Timeline: 2 days
Budget: $10~30
