Have worked in Tizen since its beginning around 2013. Tizen is based on Samsung Bada OS for which I created several apps in C++ and won a worldwide Samsung technical competition for $100K prize. As a result of that, Samsung asked to port my 30+ apps to Tizen OS. I continued developing for Tizen mobile and also developed some Smart TV apps. In 2017, my 12 apps were downloaded more than 1 million times.
