Ružnić studied in Cazin, then graduated in criminology at the University of Sarajevo. In 2016, he obtained a master's degree at the University of Banja Luka. He worked at the Una-Sana Canton employment agency.

Political career

Right after the 2018 general election, on 17 October 2018, the outgoing cantonal assembly removed the government of Husein Rošić, and Ružnić was appointed premier of the canton for a governing coalition which included A-SDA, SDP BiH, DF, NB and DNZ.
In June 2020, Ružnić's adviser Mirsad Topčagić was arrested by the State Investigation and Protection Agency. In March 2021, Ružnić was criticised for receiving MPs from the far-right AfD party, which had just been put under surveillance by the German secret services.
Ružnić was succeeded as premier by Nijaz Hušić on 5 December 2023, following the removal of Ružnić's government by the SDA. In September 2025, he was once again appointed as premier.
