Hi, I'm Nils 👋

Embedded systems developer & robotics enthusiast, with a focus on low-level firmware and hardware/software integration.

A few of the bigger milestones (minus plenty of smaller stuff along the way):

  • 🔧 Formerly a HiWi (student assistant) at the Embedded Systems Lab, H-BRS - debugging & testing of an embedded systems library, and designed a simple STM32 development board and adapters
  • 🔬 Previously at Fraunhofer IAIS - integrated "Spike Prime / Robot Inventor / Pybricks" over Web BLE, and simplified how robots get registered and connected across the whole system - both shipped in production on Open Roberta Lab.
  • 🛠️ Currently at Fraunhofer FKIE - designing hardware and developing firmware for a mobile sensor platform, with a strong focus on energy efficiency (not open source, unfortunately, so that's all i can say here 😅)
  • 🐍 Proud of my MicroPython C-API port for the Open Robotic Board (ORB-Project) - full native integration of MicroPython into STM32 firmware, exposing motor/sensor control to Python through custom C bindings. Robots running this port were demonstrated live at Gamescom as part of my university's public exhibit.
