PARADOX CAT is an established software supplier known for HMI and 3D graphics development services in the automotive industry. As technical lead and and mentor for the new AI R&D team, I specialized in automotive in-cabin sensing with computer vision and radars (60 GHz, UWB).

My team and I supported customers like BMW in both PoC and series development projects across the whole ML engineering workflow from sensor choice, calibration and data collection, through signal processing and training of deep learning models, and all the way to optimization for embedded deployment. Applications of our algorithms include both safety and comfort features based on driver and occupant monitoring in the cabin.

In a series development project for BMW, I developed new signal processing algorithms and edge AI models for Child Presence Detection (detecting children left behind in a vehicle) using UWB radar. My models significantly boosted the performance and efficiency compared to previous approaches and are now released in production vehicles. This success contributed to the 5-star Euro NCAP rating of the BMW iX3 “Neue Klasse”.

The Space Physics group at Kiel University designs and operates their own instruments to measure space radiation aboard various ESA, NASA and CNSA missions and analyzes their data to advance solar and planetary sciences as well as astronaut safety.

I served as lead instrument scientist for the High Energy Telescope onboard ESA’s Solar Orbiter and as a member of the research teams for the Mars Science Laboratory (“Curiosity” Mars rover) mission as well as Chang’E 4, China’s mission to the far side of the Moon. My research on solar eruptions and their interaction with cosmic rays resulted in 25 peer-reviewed papers, including four as first author.

In addition to my research, I developed and maintained Python-based data pipelines and analysis tools for multiple instrument teams, contributed to several open-source libraries (including matplotlib, pandas, sunpy and SpiceyPy), and taught lab courses in experimental physics.

rami.io (now pretix GmbH) is a young, bootstrapped company behind open-source projects such as the pretix event ticketing system that grew from 1 to 10 employees during my time there.

I started as an Android developer on the Web Opac App project, developing new integrations to support more than 1,000 public libraries around the world. Later, I also served as lead developer for the Vertretungsplan.app project, building the backend as well as Android and iOS apps to notify high school students and teachers of schedule changes in real time. Besides these two main projects, I occasionally supported development and customer support for pretix and its Android companion apps for ticket sales and scanning.
