He graduated from the State Technical Middle School "Tzar Boris III" in Sofia in 1932. During his mandatory military service in the late 1930s he gained practical experience in aviation radiotechnology. Following the end of his conscription, he worked as a radio technician and construction worker to save up to further his education. Between 1941 and 1943 he studied radio engineering at the Technical University (Technische Hochschule – Wien) in Vienna, Austria (annexed to Germany at the time).

Returning to Bulgaria at the end of World War II, he worked as an engineer at Bulgarian National Radio, registering several patents and rationalizations in radio technology. Shortly after the war he led a team of engineers who modernized the old "Radio Sofia" transmitter in the "Pavlovo" neighborhood. In 1946- 1947 he led the modernization of the radio transmitter tower in Vakarel with parts from the USSR, which resulted in the first experimental transmissions of "Radio Sofia II".
