Full Stack Developer Needed To Fix Bugs and Add Small Feature to Existing Web App

Hey, I have a web app that is mostly working but there are a couple of things that need to be sorted before I can deliver it to my client. Nothing major, just some bugs and one small feature I need added. I am not looking for someone to rewrite anything, just someone who can read existing code and make clean targeted changes. The app is built with React on the frontend, Node.js and Express on the backend, and it is using PostgreSQL as the database. What needs to be done: • Fix the login redirect bug: After a user signs in, they are sometimes not landing on the right page (occurs about 3 out of 10 times). This is a frontend timing issue. • Fix the dashboard filter bug: The filter is not returning the correct data due to an incorrect database query or API endpoint parameter matching. • Add a simple CSV export button on the dashboard table so users can download their records directly. • Ensure regression testing is done so other parts of the application remain completely stable. Requirements: • React and Node.js / Express experience • PostgreSQL database knowledge • Good communication throughout the contract • Comfortable reading someone else's codebase and getting to work without needing everything explained
