Working at an university & freelancing

Currently I'm working half-time as a scientific assistant at the Justus-Liebig-Universität in Giessen, where I'm in charge of the technical development and support of the Online-Self-Assessment (OSA) web application.

Apart from that I'm working as a Freelance Frontend Engineer looking for interesting projects using Angular, React, Redux, vue.js, GraphQL, Node.js or other current challenging technologies. So far I worked for GraphCMS (GraphQL, React, Redux) Technikfabrik (Vue, Node.js) and tripuls (React, Redux).

JavaScript developer at Amazon

Before I have been working for Amazon as a JavaScript Developer, developing and maintaining internally used web applications that were mostly based on HTML5, SASS, Angular & ECMAScript 6, using Grunt, ElasticSearch and Java.

Frontend Engineer at a creative agency

During my master degree and after my studies I have been working for die.interaktiven GmbH & Co. KG as a Frontend Engineer. At that time the creative agency had a variety of customers that I worked for like Leica, Mövenpick and SMA.

Most projects I have been involved in where using the Salesforce platform or TYPO3. My technologies of choice were Angular, JavaScript in general, Node.js, Gulp, Grunt, HTML5, CSS3, SVG, PHP, and sometimes it still had to be Flash.

Finishing studies as a Master of Science

While doing my Master of Science degree im Computer Science and Media at the Technische Hochschule Mittelhessen (THM) my focus were web based applications and data mining.

One of my projects was a browser based video editor realized with Backbone.js and Node.js. Another time I used an Arduino, WebGL, Java, Processing and WebSockets to control animations on a LED cube/matrix.

There even was an Adobe Air based application connected to a multitouch table via TUIO to control presentations I was involved in.

My final thesis was about distributed computing in web browsers and involved a lot of – at that time experimental – technologies, mostly JavaScript, WebRTC and Webworkers.

First experiences at a web/flash agency

Back in the days when Adobe Flash was still a thing, I was a working student at Scholz & Volkmer where my main tool of course was Adobe Flash, ActionScript 3, After Effects and sometimes Adobe Flex. At that time I learnt a lot about graphics, videos and animations when creating advertisements for Panasonic and Coca Cola.

Starting to become a Bachelor of Science

Apart from learning the basics of computer science I wrote my bachelor thesis about a mesh network of Arduinos pushing real time data to the browser using WebSockets or Adobe Flash – because at that time WebSockets' support in browsers wasn't that great.
