Ceased his study up to second class, started work and during the Liberation War he had enrolled a volunteer. In 1885 he took part in the Serbian-Bulgarian War. For a certain period he was a trader of foodstuffs and tobacco. He renovated his father’s old flour- mill and became the first one who produced white flour without bran. In 1891 Hadzhiberov went to Germany and bought five weaving looms, dynamo and electric bulbs with coal wires. He assembled them into his father’s flour- mill and the first electric bulb in Bulgaria was lit. In 1892, together with Andrea Momerin they raised a factory for production of fine European fabrics. In 1902, Hadzhiberov bought Momerin’s share and became an owner of the factory and up to 1904 he increased the number of weaving looms to 45. In 1906, alongside the Yantra River he built a water- power electric station – the first one in Bulgaria for industrial purposes and the first one built with Bulgarian private capitals. He supplied electricity for his factory and the buildings around it as well as the central part of the city and living houses. The station survived even after Nationalization.
