Building reliable embedded systems in C/C++/Rust. Passionate about embedded Linux, real-time firmware, and industrial communication. Currently implementing an open‑source IO‑Link stack in Rust.
- Rust for Embedded Systems
- Real‑Time Firmware Architecture
- Industrial Protocols (IO‑Link, MQTT, IGMP, LLDP)
- Bootloaders, OTA & Secure Updates
- Visualization tools (e.g., RigVe)
- Low‑level debugging, optimization, HW/SW co‑design
