Full Stack Developer Needed to Fix Admin Panel Bug

We have an existing back office admin panel built on React and Node.js and need a full stack developer to fix a specific issue. Our data table is not filtering correctly on the backend - the REST API returns unfiltered results when query params are passed from the React front end. We need this fixed and tested

We are looking for a react developer and full stack developer who can jump into an existing codebase quickly.
The front end developer side is React with TypeScript and Tailwind CSS. The backend is Node.js with a PostgreSQL database. The full stack developer we hire should be comfortable reading existing code, identifying the bug, and delivering a clean fix - no full rebuild required

This is a small scoped task for an experienced web developer or full stack developer who has worked on SaaS admin tools, back office systems, or internal dashboards before. A react developer who understands how REST API query params flow from a front end developer interface to a Node.js backend will get this done quickly.
We are not looking for a wordpress developer or a mobile app developer - we need a pure full stack developer with React and Node.js experience

If you are a reliable full stack developer and react developer who can review existing code, fix the bug, and explain what was wrong, we would like to talk.
There is more back office development work coming - this is a good entry point for a long-term engagement.
Please share your experience as a full stack developer or web developer with React and Node.js admin panel projects
