Nikolić finished elementary school in Senta, and continued his education in Pančevo, Maribor, Munich and later went on to Vienna and enrolled at the Polytechnic but did not finish his studies.
[4] In early 1892 Nikolić moved from Belgrade to Sremski Karlovci, which was the spiritual capital of Serbs of Vojvodina.
At the behest of his godfather[5] or cousin[6] Patriarch Georgije Branković, he designed and built numerous buildings in Sremski Karlovci and other parts of Vojvodina, including the Patriarchate Court.
[7][8] The architecture of the Patriarch's Palace (1892) belongs to the neo-Renaissance and the Secession, although the author found his inspiration on the boundaries of the Renaissance, and among the Romantic and Byzantine symbols.
After constructing the Bishop's Palace according to the principles of Theophil Hansen (1901), he remained faithful to the spirit of neo-Romanticism, the Byzantine tradition and the Secession.
