I worked in IT for 30+ years until I retired early in 2007. My last job was as CTO for EDS Services Europe, where I also helped to lead the EDS Enterprise and Systems Architect programs. Since retiring I have been active in a few Open Source Projects, though I've largely wound these down. I got sidetracked in building my own passive-class house which we moved into in late 2017. I help to run a UK self-build forum.
