Summary
🤩
Rockstar🎓
Top SchoolFlorian Heilmann is an embedded software engineer with a decade of experience specializing in real-time systems, IoT, and firmware for 3D printers and embedded devices. Based in Ludwigshafen, he contributes actively to high-profile open-source projects like Marlin and Klipper—adding features such as autotemp, Z-fade improvements, SAM4E8E microcontroller support, and TMC2660 driver integration—and has enhanced WLED with advanced audio-reactive microphone support across multiple interfaces. His work blends low-level hardware interfacing (GPIO, I2C, stepper drivers) with practical user-facing improvements in firmware and settings UX. A tinkerer and member of the VoronDesign community, he brings research-minded rigor to production firmware and a knack for making complex embedded behavior both robust and user-friendly.
