Embedded HMI and firmware engineer. For 5 years I was the sole software owner of the instrument clusters that shipped on heavy agricultural machinery: C firmware, J1939, the graphics layer, bench and field.

Shipped examples: a Cummins engine and a DANA transmission commanded from our own HMI/VCU, and a Bosch CAN valve module that removed the per-unit OEM controller and the European HMI license.

I also built VisionUI, a desktop UI framework: custom 2D engine, WYSIWYG editor, licensing and cloud backend. Performance-critical parts are in Rust, and the editor wires layers through MCP.

Looking for embedded, firmware, industrial HMI, Qt/QML, or desktop product work. Full-time or contract.
