Full Stack Developer Needed - React & Node.js Healthcare App Quick Task

We have a bug in our healthcare web application that needs a full stack developer who is comfortable with React on the frontend and Node.js on the backend. Experience with healthcare systems is a strong plus - EHR/EMR integrations, patient portals, scheduling, or billing. You should be able to jump into unfamiliar code and figure out what is happening fast. One focused task. Repo access right after offer accepted. Share examples of React and Node.js work - healthcare experience especially welcome.
