Software Developer in Los Angeles, CA, United States

Member since February 5, 2016
Ulrich has been building interactive experiences on the web since the Flash player was the only possible solution. After 2012, Ulrich moved into the Flash-less world of HTML5 by bringing his experience to the new possibilities of the canvas element, SVG, and HTML5 audio and video. In his opinion, what used to be Flash sites are now SPAs built with JavaScript, and in 2016, Flex executables were replaced by Electron.js.
Ulrich is now available for hire

The most amazing...

...site I built was a custom map of user video upload locations displayed via Mapbox/D3.js, with canvas elements, and a drill-down to the submission for a raffle.
