    I started learning development when I was 15. At first it was simple HTML pages, then I played with different CMS web platforms such as WordPress or Joomla. When I got my first Android device I decided to learn more about mobile development. Over the last 5 years, I developed a wide range of mobile apps. From simple torch or web view apps to GPS loggers, geolocation apps, social network apps, etc. My core competency lies in complete end-end management of a new mobile application development project, and I am seeking opportunities to build apps from the ground up for you or your business.  less
