Designed & implemented a full-stack web app that enables battery production research - by collecting, structuring and exporting live data from industrial machinery.

Enabling Industrial Connectivity: Reverse-engineered several proprietary industrial protocols & implemented them into an easy-to-use OPC UA server.

A web app I developed to manage our residence hall: efficiently automates user, WiFi & firewall management, integrated with iptables & FreeRADIUS. Provides Single Sign-On (SSO) for several other apps.

Completely overhauled the networking infrastructure of my residence hall: from procuring new servers & switches, designing & building a WiFi infrastructure with over 30 APs & Single Sign-On, managing IT security to installing hypervisors & Docker.

Distributes password recovery among hundreds of GPUs. Automatically bids on the best price/performance GPUs at vast.ai, continuously adjusting for measured performance.

Built a web app to visualize buildings & energy usage of the Jülich Research Centre (FZJ). Scales to hundreds of thousands of data points, per building.

Several upgrades for a K40 laser cutter: added an Arduino-powered LCD interface for precise power regulation; achieved increased accuracy and cleaner cuts through camera, line lasers and air assist; and completely replaced the internal controller, enabling higher-resolution engravings.

Helps you avoid distractions by blocking pages with your router. Provides a convenient web UI & uses SSH to manage DNS entries on any OpenWrt-capable device.

Deliver perfectly timed audio effects at your next theatre performance. Prepare a list of audio files on your PC and configure fade-in & -out, volume levels and more. A companion Android remote app allows you to start playback at the touch of a button.

Displays live data from your multimeter & exports it as CSV. Works with the tools my high school had at the time: Voltcraft VC840 and ME32, by implementing their custom RS232-based protocols.

In ninth grade, I collaborated with a friend to build a robot that scans a Rubik's Cube with a webcam and autonomously solves it. While he built the hardware, I was responsible for the software.
