[Employment]

I would like to work professionally as a security researcher/bug finder. 



See my resume at my site. I am very eager to work, flexible, and 

extremely productive. I have a top notch resume, with credentials 

from leading bug finders. I am willing to work per contract, relocate, 

or telecommute. 

 

[Give a Hand]

I haven't got a job as a security researcher yet and my family don't support my security work - so, I don't have a computer of my own. Please consider about donating at:
