from idea to working unit
From concept to working module: circuit design, PCB layout, firmware, panel and enclosure. You get the complete project — schematics, sources and documentation included.
Firmware development in C, C++ and MicroPython for STM32 and RP2040 — audio and CV processing, peripherals, displays, communication buses such as CAN.
Feasibility studies and rapid prototypes: testing an idea on a development board before you commit to hardware.
Three decades of professional software development — frontend frameworks, architecture, migrations and team leadership. See my skills, education and project history.
open and documented
My development process is public: the build logs on this site document how I approach a project — step by step, including the detours. If you want to know how I would handle yours, the logs are the most honest portfolio I can offer. The methodical side (planning, agent-assisted development, knowledge management) is described in Agentic Coding.
no formalities needed
A short mail describing what you have in mind is enough:

You will get an honest assessment of whether and how I can help —
and if I cannot, I will say so.
