Kushi was born 1885 in Shkodër, where he spent his childhood and received first art impulses through the paintings of the famous Albanian painter Kolë Idromeno.
He studied Fine Arts between 1912 and 1914 in Belgrade, when he was forced to interrupt the lessons due to the outbreak of World War I.
He moved back to Albania and became a teacher of Fine Arts at the Gymnasium of Elbasan, and later on moved to Tirana in 1931 and the same year he established the first drawing school in the country, which some months later in 1932 became the official Fine Arts School of Albania (Shkolla e vizatimit).
The success of this exhibition led him and other painters to the creation of the Friends of the Arts Society (Shoqnia Miqt’ e Artit), which had as a primary goal the foundation of a national gallery.
Very famous are the paintings Portret vajze (Portrait of a girl) and Bariu me shkop (Shepherd with a Staff).
