A Spotify client that recommends as well as it retrieves.

Song recommendations come from an ML model; the app shows user playlists and queries songs and artists with preview playback, over the Spotify API and third-party libraries.

CRUD over employee records, a ticket system, a calendar and asynchronous email jobs, built as one full-stack Spring and Vue application.
