After playing youth basketball with the junior teams of Nea Kifissia, Chatzinikolas began his professional career in 2011, with the Greek Second Division club Nea Kifissia's senior men's team.[1] In 2014, he was loaned to Pagrati.[2] He left Nea Kifissia, when the club was relegated down from the first-tier level Greek Basket League, to the third-tier level Greek B League, due to financial problems.
On August 3, 2016, he joined Koroivos Amaliadas.[3] On September 10, 2019, Chatzinikolas returned to the first division, signing with PAOK Thessaloniki.
On July 27, 2020, he transferred to the newly promoted team of Charilaos Trikoupis.[4]
Chatzinikolas spent the next two seasons abroad with the Austrian club Oberwart Gunners and the German club Panthers Schwenningen.
In early 2023, Chatzinikolas returned to Greece for Kolossos Rodou. In 7 games with Kolossos, he averaged 1.7 points in 11 minutes per contest. On July 13, 2023, he renewed his contract with Kolossos. On July 3, 2024, he renewed his contract with the island club once more.
With the junior national teams of Greece, Chatzinikolas played at the 2013 FIBA Europe Under-18 Championship, and the 2015 FIBA Europe Under-20 Championship.[5]
