Full-Stack Web App Enhancement

My web application is live but the backend needs serious attention. I want a seasoned full-stack developer who can dive into a Node.js codebase, refactor what’s there, extend it with new endpoints, and wire everything up to MySQL. While the UI already works, you’ll still touch the front end whenever an API change surfaces, so confidence on both sides of the stack is essential. Core objectives • Strengthen and expand existing backend functionality in Node.js (Express) • Model new MySQL tables, write performant queries, and handle migrations safely • Integrate third-party services for payments, email, and authentication without breaking current flows • Keep the interface responsive by updating shared React components alongside any API changes • Ship production-ready code—unit tests, clear commits, and smooth CI/CD deployment are non-negotiable • Share concise, regular progress updates so we stay perfectly aligned You’ll receive full access to the repo, staging database, and API keys for the third-party providers. Success means I can push the new build to production confident that the backend scales, endpoints respond quickly, and the user experience stays seamless. If you thrive on polishing Node.js backends, enjoy working with MySQL, and don’t mind tweaking the UI when needed, let’s talk.
