Lead Frontend Developer — TamTam (part of Dept) May 2016 — Sep 2016

Grew from Senior to Lead within the company. Quality assurance, optimising workflows and sharing my knowledge within multiple teams — pushing the projects to its next level.

Getting development alligned with design is key and enables us to deliver high standard products.

Technical Director — Supersteil Feb 2014 — Mar 2015

After some years at Supersteil and a growing studio, I got promoted to Technical Director. Meaning I was still working on project, but also putting more time and effort into directing technical projects and investigation the technical part of the studio. These are things like our workflow and the way we could optimise and automate steps during development. Also, innovating and new (input-) devices have high priority.

Senior Interactive Developer — Supersteil Feb 2009 — Feb 2014

Developing great experiences with PHP, HTML5, CSS3 and Javascript, for both web and mobile / touch. Always looking for new challenges with which I could raise a project to a higher level. Using as less as images as possible and scripting custom codes optimizes the UX in many ways.

Developer Internship — Supersteil Sep 2008 — Dec 2008

A four month internship at Supersteil in my third your of college. Worked on several projects and learned a lot about Flash and Databases. (Which was cool back in the days.)
