Peristeri was born in Korçë, at that time still part of the Ottoman Empire to an Albanian family of the Eastern Orthodox rite. Initially he worked as a tinsmith, and later as professional soccer player. He was involved with the Communist Group of Korçë, one of the earliest in Albania. He was one of the founding members of the Albanian Communist Party in 1941, and took an active part in World War II as a partisan of the National Liberation Movement (LANC). After the founding of the People's Republic of Albania on 11 January 1946, Peristeri was elected in the People's Assembly (Alb: Kuvendi Popullor) in 1950. He retained this membership until the eleventh legislative period which would end in 1991. He was a representative of the Pogradec District. In addition, he was a member of the Central Committee (CC) of the PPSh.
At the 2nd Congress of the PPSh in April 1952, he became a candidate-member of the Politburo of the Party of Labour of Albania. He retained candidate membership within this highest body of the Party leadership until November 1981.
Peristeri was re-confirmed at the 4th Congress of BSSH in February 1955 as the Chairman of the General Council of Trade Unions. On June 22, 1958, he was succeeded by Gogo Nushi. Nevertheless, Peristeri himself remained a member of the Secretariat of BSSh and was also elected chairman of the Party Control Commission of the PPSh. On the 5th Congress of Trade Unions in April 1961, he succeeded as member of the Presidium of the General Council, but withdrew from the Secretariat.
In addition, he was temporarily Deputy Chairman of the Presidium of the People's Assembly, and thus representative of President Haxhi Lleshi. Peristeri, which belonged to the inner circle of the so-called "old guard" of the party, was also a companion of Enver Hoxha, First Secretary of the PPSh, and Prime Minister Mehmet Shehu during business trips in the country, as well as social events. He was disaffectedly called "Uncle Pilo" by the people.
