When Ibrahim Alhemyari began working in tech, barely anybody else understood what he did. It was 2006 and his home country of Yemen, torn by decades of coups, conflicts and civil wars, was 26 years into the presidency of Ali Abdullah Saleh, a strongman who had risen to power after the assassination of predecessor Ahmad al-Ghashmi.
