I (co-)maintain Apache2, PHP, MariaDB, Cyrus SASL, Cyrus IMAP, Berkeley DB and all things DNS in Debian and also have semi-official PPAs for those packages (PHP). I have been member of Debian GNOME GTK+ packaging team. (In other words I've seen things you people wouldn't believe. :-))
I am author of two apache modules (mod-vhost-ldap and mod-log-spread2) and I am co-author of Knot DNS, a fast authoritative-only DNS server, and now I work on BIND, the most used DNS server on the Internet.
I have expertise in routing, DNS, DNSSEC, Debian packaging and much more to list here :).
If you like my work and want to give me a little motivation, you can spoil me using PayPal.
I break things. I fix things.
