About Me

I am a professional software and web engineer specializing in the JavaScript ecosystem. After obtaining my degree in software engineering, I have been working in the industry for over 7 years now in various roles from frontend to backend and I really enjoy it.

I have been involved in all aspects and I built a wide range of solutions including:

Contentful business websites, distributed full-stack web applications, microservices, advanced automation, and testing solutions, cross-browser extensions, large-scale tag management and audience measurement systems, and custom CMS systems.

Apart from my role as a software engineer, I love working on collaborative ventures and side projects as well as sharing my learnings and experience with the community.


These are a few side-projects I collaborated on and built for clients. I love a good challenge and these are great opportunities to experiment with different technologies and approaches.


    Emoji To Favicon

    Based on a fun idea by Lea Verou to use emojis as favicons, I took a deep dive into Vue 3 and built a web app around that idea. I learned how emojis work in Unicode and how to modify the sequences to change the appearance and color of emojis. I built a web scraper to get the latest emojis from the Unicode website and refined my skills in Vue 3 and Vue state management. And I collaborated with the designer Paul to create a fun and colorful design.

    Clock of Change - Human Connection

    The Clock of Change aims to visualize the progress of the Human Connection project in a playful and interactive way. The Frontend is based on WordPress plugins. I implemented a lot of features and improvements like filtering, sorting, a new country counter plugin, fullscreen mode, improved animations, and lots of layout improvements for the client. I also worked on the Backend (Node.js) to improve the API and the data structure and containerize it.

    Superkühe - WDR Sensorstory

    Ambitious and hilarious at the same time: we created an automated dairy cow reporting system in a world before AI for the client WDR (Westdeutscher Rundfunk), which attracted significant media coverage. I learned Ruby on Rails specifically for this project, developing an automated system that fetches sensor data from the Smaxtec API (linked to real dairy cows) to generate reports. Additionally, I built a chatbot using my own API based on the sensor data and contributed to the infrastructure.
