I started working with Linux and *BSD in late 90's, I worked as Linux and FreeBSD system administrator in a software house.
In 2005 I founded my own software house, we create web solutions, hosting and ICT solutions.
Starting from 2008 I am an OpeBSD committer and I develop ports and some system daemons.
In 2012 I published 3 articles for BSD Magazine about npppd(8), a pptp/l2tp vpn daemon, mysql-zrm and nmap.
I also gave some talks about relayd (in 2012), npppd (2013) and LibreSSL (Cebit 2015).
I gave talks about OpenSMTPD, Elasticsearch and seccomp in 2015, 2016 and 2017 Linux Europe summits.
In 2018 I became an Apache developer for the SpamAssassin project.
