Isjtar works as an independent media artist, electronic music composer and performer.

From 2006 to 2011 he was a core member of OKNO, an artist run organization for art and media technology.
OKNO organized a large number of events, ranging from exhibitions to workshops and collective creation. Main themes were connected artworks, interactivity, ecology, physical computing and electronic performance. As part of the many collectives harboured by OKNO, Isjtar participated in events such as dEAF07, Cynetart06, Sonambiente06, Upgrade! Chainreaction Skopje, ZKM Flying Circus, Time Inventors’ Kabinet.

In 2011 he decided to dedicate himself fully to his artistic practice, focusing mainly on ATK!, a duo with Ofer Smilansky.
ATK! made site specific art, fusing light and sound in immersive performances and installations. Among the events were Lexus Hybrid Art Moscow, MNF De Munt and Biela Noc Bratislava.

At the end of 2016 he left ATK! to research new forms of expression, using game engines.

In 2019 Isjtar started working at CREW, an organization pioneering VR and experimental techniques in the theatrical arts. In collaboration with lead artist Eric Joris, he heads the Lab section of CREW.

As an expert in experimental media, he has taught workshops, given lectures and published several articles on the topic.
