Full stack developer at WONDROUS LLC
Started to user Drupal in late 2014.
I give talks there, as well at the drupal meetup in Zurich since mid 2015.
At the Drupal Dev Days at Milano I had a talk called "Drupal 8 theming with Twig and Sass". It was recorded.
Even before my drupal activities I held talks about JS and CSS ranging from short 15min to full hours.
