How joaoptoaldo/sistema-facul works

Sistema Universitário is a React web app backed by an Express API and SQLite. Users navigate university pages to register students or professors, browse courses, and submit contact messages; those pages call the corresponding API resources. The backend routes requests through controllers and business services to repositories and the database. The README documents the UI capabilities and API endpoints; sampled source confirms several layer calls, while some page-to-API links are documented rather than visible in the excerpts.
