Information Visualizer - Data Scientist - Software Architect

About


Hi, I am a passionate information visualizer and experienced software architect. I finished my PhD in Computer Science with a focus on Information Visualization in 2017 at the Johannes Kepler University, Linz, Austria. I love to dig into code, hunt bugs, and design new platforms. In addition, I teach Information Visualization classes at universities.

I like to develop libraries and applications that in one way or the other help others. Like applications that help scientists to explore their datasets and find new insights. But also libraries that help developers to create those applications more easily. I value clean structured code that is easy to read and maintain.

Typescript is awesome so are Python typings. I'm fluent in frameworks and libraries such as Vue.js, React, or D3 but also the ability to quickly adapt to other environments.

I'm currently looking for a new challenge in my life. So, if you have some interesting and challenging projects and job opportunities, shoot me a message.

Today I got accepted for the Github Sponsors initiative. Github Sponsors allows that people support coder they like and wanna help them to continue their work and show their appreciation.

2019-09-05 - new Chart.js plugins

I created three new chart.js plugins: chartjs-chart-graph (for showing graphs and trees), chartjs-chart-error-bars (add error bars for various base type), and chartjs-chart-geo (create cholorpleth and bubble maps). They were also added to chart.js awesome list.

2019-07-01 - Monash Research Visit

Just came back from my research trip at Monash university in Melbourne, Australia. Thanks Tim Dywer for hosting me, again. I worked on some cool projects like the MicroGrid with Sarah Goodwin and Barrett Ens or on a web version of MiniZinc with Guido Tack.
