How mehedi-hasan-raju/langauge-learning-website works

This is a German-learning backend API. Clients call the mounted HTTP routes; feature controllers handle requests and delegate domain operations to services, with authentication and shared infrastructure supporting those operations. The product spans structured lessons and exercises, user progress, subscriptions, and supporting content such as Ausbildung, visa checklists, and blogs. The README is empty, and many source excerpts are incomplete or unavailable, so the graph preserves documented-by-tree capabilities while omitting unverified internal links.
