- Existence can be improved by technology.
- Strong crypto belongs to the people.
- Strive to save our planet, otherwise everything else is pointless.
- Always consider Open-Source.
Sometimes I blog at chrz.de, and rarely check LinkedIn. Reach me via Matrix at @stargate01:matrix.org.
Most of the time I work for zeromouse.ai, vivokey.com, dangerousthings.com, and whatever I find interesting:
- Hardware, firmware and interface engineering
- ESP32 (IDF), RP2040, NXP PN* and SmartMX chipsets
- NFC, RFID and LoRa
- KeePassXC and YubiKey tools
- WebAuthN, FIDO2, and CTAP
- Custom firmware for NRF52-based smartwatches
- 3D-Printing, CAD and CAM
- Linux Servers, NixOS, Docker, essentially Devops for myself
In my time at TUM I focused on large-scale high-performance development, specifically for computational fluid dynamics.
