Been working at FSport (www.fsport.net) since late 2016, mostly web development but also responsible for both android and ios apps and the graphic design. We probably got one of the most complex Polymer site out there with live updates, and multiple custom elements interacting with each other.

Background as graphic designer, and learned swift, kotlin, android java, java, C++, php, mySQL, and many more over the years. For javascript, I also have understanding in React, Redux, Vue, jQuery, and Angular 1, among the standard web based knowledge.
