Worked as a freelance software engineer on metasearch engines for various companies and on many other small personal projects like social networks, news aggregators and computer vision software. Fun fact: A small piece of custom search engine software that I developed and sold for $15 online, was also used by a company in Turkey (Geliyoo) that got €2.500.000 funding from the government. It became a quite popular story in Turkey for a while!
