Hi!
I'm Paul — developer, mechanical engineering student, photography enthusiast, and founder of a small startup focused on solving everyday problems (and having fun along the way). This site is a peek into my life and work. You can find me around the Bay Area or Hamburg, Germany. Feel free to reach out for collabs or just to say hi!

Advent of Code 2025, solved in C
Solved all puzzles more or less optimized in C, see day 10/2 as an example of the approach taken.
Heidelberg Citizen Data Groundstation
First-of-its-kind initiative to collect and analyze self-collected data directly into the city of Heidelberg's Citizen Data Platform.
MyFrame: An Open-Source HomeKit Compatible Picture Frame
I reverse-engineered the HomeKit protocol to create MyFrame, an open-source picture frame that seamlessly integrates with Apple's HomeKit ecosystem. MyFrame useses a static image with different white points to show different themes.
Chirpanalytica
Finalist project at the German Federal AI Competition that used a NLP approach to match unpolitical tweets to differnet political viewpoints.
OSAMD: Open-Source Air Monitoring Device
During the peaks of the COVID-19 pandemic, I developed OSAMD, an open-source air monitoring device designed to measure indoor air quality and provide real-time feedback on ventilation effectiveness. The basic idea was to use a very cheap sensor and map low-quality sensor data to hihg-quality sensor data using large datasets. Build around 10.000 Times in 200+ workshops, maily in schools.
LixieClock
Low Voltage Nixie Clock: A modern take on the classic nixie tube clock, designed to operate at a safe low voltage while maintaining the vintage aesthetic.
TweetGuesser: A Twitter Game
Small project at Jugend Hackt Frankfurt 2017, where players have to guess the author of a tweet from a selection of four possible authors.
