Nice to meet you. I’m a researcher, software developer, photographer, and musician living in Darmstadt, Germany.
I’m deputy head of the competence center for Spatial Information Management at Fraunhofer IGD and a lecturer at the Technical University of Darmstadt. I have a PhD in Computer Science. My research interests are in processing of big geospatial data, workflow management, distributed systems, and cloud computing.
In my spare time, I’m a passionate musician and photographer. I also work on several open-source projects and contribute to popular frameworks and libraries. Feel free to contact me if you want to know more.
Notoriously curious me exploring the world.
A question I was once asked (“Is Cloud Computing ethically justifiable?”) led me to create this presentation about Smart Cities that use Cloud Computing to make the urban environment more livable.
A tutorial I gave at the Web3D 2014 conference in Vancouver, BC, Canada. I presented different tools to prepare and visualize big 3D city models in the Web. The slides start with a motivating example but the largest part of the talk was live coding.
In this presentation that I gave at the Utility and Cloud Computing Conference UCC 2014, I talked about a novel user interface based on Domain-Specific Languages (DSLs) that allow domain experts to harness the capabilities of Cloud Computing.
These are the things I do.
This plugin adds a Download task to Gradle that displays progress information just like Gradle does when it retrieves an artifact from a repository.
citeproc-java is a Citation Style Language (CSL) processor for Java. It interprets CSL styles and generates citations and bibliographies, for example, from BibTeX files.
Steep is a Scientific Workflow Management System I’m working on at Fraunhofer IGD. It has been a core part of my PhD thesis. In 2020, we decided to release it under an Open-Source license.
I’m the official maintainer of the Vert.x website. Vert.x is a tool-kit for building reactive applications on the Java Virtual Machine.
GeoRocket is a high-performance data store for geospatial files. It’s a project I work on with my team at Fraunhofer IGD.
Spamihilator is a free Anti Spam Filter that works between your email client and the Internet and examines every incoming message. Useless spam mails (Junk) will be filtered out.
In my other life, I’m a passionate photographer.
I love travelling, hiking and exploring. My constant curiosity has led me to some incredible places on Earth—mostly in Europe and in colder, northern areas of the planet. I mostly do landscape photography but I often also visit beautiful cities.
My bucket list is long (maybe too long) and I try to roam the world as much as I can. Staying outdoors in the nature and experiencing photography adventures has become a part of myself that I cannot imagine to lose.
I love singing and playing acoustic guitar.
I spend my spare time with the rock band Rejected Papers. We do covers of various artists and occasionally play a gig in our local area. If you want to see us or book us for your event, feel free to contact me.
In addition, I have a YouTube channel where I upload acoustic folk songs and singer-songwriter covers from time to time. Feel free to subscribe, if you like my videos. Thanks!
