I am a self-employed IT professional and author of computer books. I enjoy "hands-on" projects the most, working as a software developer, but I also have experience as a system architect, analyst, designer and consultant.

I spend some of my time working on problems in theoretical physics. I published several papers in leading journals, collaborating with researchers from notable institutions such as NASA JPL.

I grew up in Hungary but moved to Ottawa, Canada in 1987, where I live with my wife Ildikó.

A reasonably up-to-date version of my resume provides an overview of my professional activities. I also maintain professional profiles on LinkedIn, ResearchGate and Academia.edu, and a personal profile on Facebook. I am also a regular contributor on Quora, (see also my Quora Blog) where I have been named a "Top Writer", with several of my answers published by Forbes, the Huffington Post, MSN, and other news media outlets.
