I am a programmer specializing in privacy. I fell in love with programming in 1995, with Bitcoin in 2011, and most recently with Monero in 2017.

I prefer to reason from first principles. I tend to see through the bullshit and manage technical trade-offs well. Here is my github, twitter, reddit, and medium.

Disclosure

I do research and encourage the use of a variety of anonymity and privacy enhancing technologies, including but not limited to overlay networks like Tor and VPN-s; anonymity enabling operating systems like Whonix and Tails; financial privacy respecting cryptocurrencies like Monero; privacy techniques like coin-joining; private secure messengers like Signal; and decentralized cryptocurrency exchanges like Bisq.

I believe privacy and freedom of expression are basic human rights, including in their absolute forms, because who is there to judge? One person’s freedom of expression, obviously, does not limit other person’s freedom to establish any rules and limits within their private properties.
