Angelo Tadres is a Chilean software engineer with more than 7 years of professional experience. Hailing from Santiago, Chile, he began his career in R&D for video games meant to assist the blind and visually impaired with their orientation and mobility skills. After a quick pass through the telecommunications industry—working in value-added services and mobile applications—he received the opportunity to join the Santiago studio of DeNA, one of the world's largest mobile video game companies. In 2013, Angelo was asked to move to Vancouver, Canada, as a lead software engineer, where he helped to build the fledgling Canadian studio to a team of 90, and in particular, championed Unity 3D, paving the way for other teams' adoption and use of this technology. He's known for getting things done, shooting first and asking questions later. When he is not coding and pushing to GitHub, you'll find him playing table tennis or running along the sea wall.
