Senior🎓
Top SchoolIan Jeffray is a Director and seasoned software and firmware engineer with 20 years' experience building embedded systems, Linux and Windows applications, and real-time microcontroller firmware from concept through production. Based in Livingston, Scotland, he combines hands-on low-level development (kernel ports, bootloaders, drivers) with systems-level design and hardware bring-up, and leads his consultancy Codion Ltd delivering cross-platform solutions. His background spans consumer products, mobile graphics and video systems, networked video recorders, and commercial game development—he even ported RISC OS games to iOS and shipped GameBoy Advance cartridges. An active maintainer of practical tooling, he contributed Perl-based converters for PCB schematics (Altium to KiCad), demonstrating attention to detail in format fidelity and edge-case handling. Known for solving timing-critical and resource-constrained problems, he blends entrepreneurial product sense with deep technical breadth across OS, firmware, and electronics domains.
