Job offers I accept

I don't accept full-time jobs. I rarely respond to these emails and I usually I don't even read them. My CV isn't maintained anymore, I can't send it.

But as a freelancer I consider offers like "we have X, we want X±Δ, we can pay Y and we can wait Z days/weeks/months".

Where Δ is something I wrote (or will write) in my books/blog posts about. Y can be surprisingly low, by the way. And Z is limited by couple of months.

So if you want me to do something for you, please drop me email, stating X, Δ, Y and Z clearly, at least, X and Δ.

Also, I do nothing without advance payment.

Despite the fact I've written RE4B, and found several CVEs, and once created FPGA-based Oracle RDBMS passwords cracker, I'm not in infosec, and almost never been (except for a brief experience), so it's senseless to offer me a job(s) in that area.


... as they call it in Wikipedia
