I am the lead (and only) developer of a social project for architects. It has all the nifty social features like the facebook and twittter and I am the only one coder.

If that don't make me a little bit like Mark, what does? (just joking)

I am developing web and server applications for our affiliate network.

I am also the guy who installs mikrotik to manage our office network, who install ifolder to have our shared files anywhere in the world like dropbox but with our privacy terms.

I was the co-founder and CTO of a small company (~ 20 employees).

I was bringing all the geek stuff to the table :)

I was a lead developer team of 5 for mainly creating online applications and interactive web sites. I also managed several linux servers.
