I was born in Zenica, in the former Socialist Republic of Bosnia and Herzegovina (SFR Yugoslavia), in August 1970.

My family roots are in Bosnia and Herzegovina and in “Old Herzegovina” — today partly in Montenegro (Sutorina and the Bay of Kotor area). By paternal line I belong to the I2a (I-P37) Y-DNA haplogroup, common among Balkan males, and my maternal mtDNA haplogroup is J1c2e.

Since 1977 I lived in Croatia with my parents, Gordana (Pehar) and Radivoje Kosić. After the breakup of Yugoslavia I retained Croatian citizenship.

In the early 1990s I studied economics and tourism in Dubrovnik and law in Sarajevo, shortly before the war. Later, between 1998 and 2001, I completed studies in informatics and design at the Polytechnic in Zagreb.

I was raised as an atheist. Religion was not particularly important in my family (Catholic and Orthodox backgrounds), yet because it played a major role in society around me, I studied it for many years out of curiosity and a desire to understand it.

I was baptized in the Seventh-day Adventist Church in Sarajevo in January 1992, but I never developed a collective religious identity. My interest in religion has always been individual and philosophical. I consider myself a gnostic rather than agnostic: my worldview combines insights from many religious traditions, searching for what is universal and shared among them.

Since 2010 I have lived in Frankfurt am Main, Germany. I married a Bosnian woman in 2012.

Over the years I have worked in different fields: as a web developer and designer, aircraft ground handler, shipping and receiving clerk, and currently as a security agent.

My hobbies include listening to and playing music, reading and writing, photography, painting, and collecting rare cacti.

I speak Bosnian / Croatian / Serbian / Montenegrin, English, and German, with some knowledge of Italian and Spanish. I enjoy learning languages and exploring etymology.

In 2007–2008 I worked with my wife and friends in the association Kulturfokus on the creation and publication of the bilingual monograph “Tales of Stone” (“Kamenim tragovima” / “Auf steinernen Spuren”).

In the future I plan to publish several small books: a collection of my poetry, short stories, a book of Balkan jokes, and a book about rare cacti.
