About John De Graaff

I am a very non-typical technology enthusiast ; I like learning things about technology (and about nature, and math, and philosophy, and psychology, and then some)I like to design things using technology.I like to build things using technology.And I like to create (invent / develop) new technology!So, I am kind-of a "nerd", but then a very socialised one, who is very (very) good with language and words (oh, and an immodest one ...) (but then again: a funny one ;- )

Listed skills include Networking, Security, Telecommunications, Network Architecture, and 22 others.
