I help companies by creating reliable, low-level, production-ready systems:

• Control system firmware
• Printed circuit boards
• Carrier boards (e.g. for the Raspberry Pi Compute Module)

Selected public work includes:

• Systems with the 6502, Z80, 6809, 68000, Raspberry Pi, and ESP32
• QCPU 2 microprocessor architecture
• Optimising assemblers and DSLs
• Time-sharing kernels and real-time operating systems
• Open Source repositories and contributions (e.g. Zig, Nginx, Vim)

Interested in hiring me for a project? E-mail me and we can babble about your idea.
