bio

my story until now, kinda autobiographic

I’m into software engineering, informatics in general, web video creation, 3d printing, metal music, skateboarding, running, bouldering, playing chess, and so much more. In the past, I co-authored 30+ research papers, I created 4,200+ videos that were viewed a total of ~60 million times, I wrote tens of thousands lines of code, and I certainly fell more than a 100,000 times from my skateboard or a climbing wall. On this page, I summarize how that came about. If you’re more interested about the present, visit my now-page, watch one of my best videos, or read a research paper.

 

the short bio

My informatics journey started at age 12 by teaching myself programming by developing small tools not so different from today. In 2010, I began uploading gaming videos, eventually growing my YouTube channel enough to make a living from it. Meanwhile, I started pursuing my studies in computer science at the Karlsruhe Institute of Technology (KIT). In 2018, I launched the while(true) podcast, sharing insights about my life in computer science. Over time, I chose to follow this passion, finishing my bachelor’s and master’s degrees, which was even awarded with the VKSI award. I also switched up the content I created, moving from gaming videos to educational content about computer science and software engineering. Following my master’s degree in 2020, I started as a doctoral researcher at KIT, where I focused on software architecture, confidentiality, data flow analysis, and uncertainty.

In my time at the university, I published at top-tier venues, did a lot of teaching, had great opportunities to coopearte with leading experts in the field, traveled extensively, and led the development open-source projects like JPlag and ABUNAI. I also learned 3D printing by accident. During this time, I continued creating content and live streaming software development, but obviously not as active as before. After defending my dissertation in December 2024, I stayed for another nine months as a postdoctoral researcher. In 2025, after exactly five years as a researcher, I transitioned to the automotive industry to gain practical experience in software engeering. In the end, I was awarded with the 18th KIT Doctoral Award for Outstanding Doctoral Researchers, recognizing my work during my time at the university. Today, I work as a Senior Software Engineer at Vector Informatik, engineering software for software engineers, and I continue to create content about informatics.

the long bio

I started programming when I was 12 years old using Visual Basic.NET 2005. With limited internet access, I learned the language and Windows Forms-based UI development primarily by reading the provided documentation by Microsoft. Back then, I programmed dozens of little tools that helped in my daily life and played with new technologies; funny thing: really not so different compared to today. My school had only very limited classes on informatics, so I was basically on my own. A couple years later, in 2009 with the age of 15, I uploaded my first YouTube videos about the game Audiosurf. They are not online anymore, but some were reuploaded. In October 2010, I uploaded my first Let’s Play video, inspired by the very young German Let’s Play scene. One month later, I discovered a game in early alpha status called Minecraft and started creating videos about it.

I finished school in 2012 as best of year in informatics. By then, I already had uploaded hundreds of videos, reached more than 10,000 subscribers, and became YouTube partner. This was quite a big thing: Everyone dreamed about earning just enough money with a let’s play series to pay for the game being played, and only very few reached the partner status. Also, I developed my very first popular software, skate’s Thumbnail Tool that helps in automating the thumbnail creation process. Nowadays, not worth mentioning, but back then it was quite well known :)

              

In 2012, I moved to Karlsruhe to study computer science at the Karlsruhe Institute of Technology – and also to do more skateboarding :). In this time, the very first big German Minecraft Let’s Play projects were started, e.g., the Mega Project or Craft Attack 1. Creating videos together with other YouTubers helped my channel to grow substantially and I reached the mark of 100,000 subscribers mid 2015. During that time, I did coding streams for the first time. While creating videos at night, I slowly moved towards reaching my bachelor’s degree at day.

The most successful time of my YouTube career started in late 2015 with a Minecraft project named Craft Attack 3 and later a project called Minecraft Novus. At the peak, my videos were viewed around 2.5 million times per month. Although I was just about writing my bachelor’s thesis about incremental model synchronization with databases, I made a living as a fulltime YouTuber by that time.

              

During this time, I had great opportunities and I experienced crazy things like visiting Japan multiple times, giving keynotes, meeting so many subscribers (and also the YouTube CEO), and building my own studio. Despite the success as web video creator, I was more interested in computer science and continued my studies at KIT, Karlsruhe. I focussed on software engineering, software architecture, telematics, and security. In 2018, half way through my studies, I started while(true), a podcast where I speak about my daily life in computer science (‘till this day!). In retrospective, it’s really impressive how many original Minecraft viewers already were or became interested in informatics – I’m sorry for maybe influencing your decision to study computer science ;)

As the end of my studies were getting closer and closer, I had to make a serious decision: Should I continue investing every single free minute into creating videos, or follow my passion for computer science? For a variety of reasons, I choose the latter. I produced and uploaded my last major video series called Beyond RTX, seven educational videos about modern graphics cards (in cooperation with Nvidia), flew to Tokyo once again, and finished my master’s thesis about defining data flow constraints for confidentiality analysis which was awarded with the VKSI Award.

              

After finishing my studies of computer science in 2020, I stayed at the university to become a doctoral researcher. I choose against going directly to industry for a variety of reasons, including my interest in research and teaching. Since then, I created significantly less videos, as my focus shifted away from YouTube. However, I still developed new content and formats, e.g., streaming regularly live while coding, or science communication using Minecraft.

As doctoral researcher, my research interests included software architecture, confidentiality, data flow analysis, and uncertainty. The central research question of my dissertation was how to consider the effect of uncertainty in data flow-based confidentiality analysis. At the university, I had many great opportunities for cooperations and possibilities to travel to seminars and conferences all over the world (literally, from Canada to Australia). I published at many high ranked venues, including the International Conference on Software Engineering (ICSE), the International Conference on Software Architecture (ICSA), and the International Conference on Software Engineering for Adaptive and Self-Managing Systems (SEAMS).

Regarding teaching, I was involved into the lecture for advanced software engineering, and I supervised team projects for software development, 20+ practical courses and seminars, and 15+ bachelor’s and master’s theses. I really enjoyed teaching - and my exercise for the the lecture “Software Engineering II” was even awarded as best mandatory exercise of the semester. I also invested a lot of time in open source software development, e.g., for the open source plagiarism detector JPlag, my own research project ABUNAI, our group’s data flow analysis, and many other projects.

              

I defended my dissertation (Dr.-Ing.) on December 9th, 2024 with highest honors (summa cum laude). Afterwards, I stayed for nine months to help in wrapping up ongoing research projects, and to lead the development teams for JPlag and our data flow analysis. Finnaly, I was awarded with the 18th KIT Doctoral Award for Outstanding Doctoral Researchers, which is awarded annually to only 3 of the approximately 600 dissertations submitted at KIT, recognizing my work during my time at the university.

After exactly five years as a researcher at the university, I left academia in August 2025 to become a software engineer in the automotive industry. Despite having a lot of fun doing research and teaching, I wanted to gain practical experience in industry, to see how software is developed in a larger company, and to learn a lot of new things. Today, I work as a Senior Software Engineer at Vector Informatik, engineering software engineering software, and I continue to create content about informatics.
