Software Engineer with 30+ years of professional experience, home computer enthusiast since about the time the dinosaurs disappeared. Living in Barcelona, Spain right now, where I have a small IT services company together with two Spanish colleagues. I write Android and iOS/ OSX applications from time to time (check out the tikal-25 pocket calculator app in the apple AppStore) and know Java, kotlin, swift, python, C, C++, ARM / 68000 / 6502 assembler, and probably already forgot more about LISP than most people will ever be prepared to know. Spent a couple of years as scientific employee at the university after graduation, then moved to a position as software engineer for command and control systems for offices of public security, and then soon went into the web project business as backend developer until recently.
