+== Introduction
+
+Hello! My name is Brent Saner, and I have a passion for technology.
+I don't mean I enjoy playing with the latest gadgets, I mean a *passion*.
+
+I read RFCs and man pages for fun (so much so that
+https://git.square-r00t.net/OpTools/tree/ref/rfc.py[I wrote an RFC client^] - before I found out that the IETF already
+https://tools.ietf.org/inventory/reading-tools.shtml[has several^], oops). I have a
+https://git.square-r00t.net/[large amount of projects^] I work on in my free time. I have a VM lab (almost a necessity
+if one works from home), and my home network is segmented into five different VLANs, four different WLANs tied to a
+unique VLAN each, on-site and remote backups, PXE-bootstrapped https://ipxe.org/[iPXE^], with 10Gbps house backbone
+using 802.1X backed by RADIUS and LDAP, all with a full x86_64 Linux 1U as my border device. For a home network.
+
+When I say "passion", I mean it.
+
+With this, combined with my 18 years of professional Linux/UNIX experience (21 years hobbyist), I've learned a few
+tricks around the ol' rodeo. Because of my adherence to and knowledge of best practices, care for forward-thinking, and
+sheer joy I take in solving potentially difficult problems, it is my goal (and particular knack) to get your company's
+infrastructure and services smooth and stable while retaining flexibility for vast growth.

+== Samples of Work
+
+Since I focus more on operations/administration than development, most of my "samples" can be found via
+administration *theory*. This is expounded upon a great deal in https://sysadministrivia.com/[my podcast^].
+
+Occasionally, however, I also write documentation for our demographic (mostly other Linux sysadmins). Samples of these
+can be found here:
+
+* https://sysadministrivia.com/news/RSYNC[RSYNC^] (not RSYNC over SSH)
+* https://sysadministrivia.com/news/howto-podcast[Podcast hosting^] (technical details)
+* https://sysadministrivia.com/news/howto-borgserver[Deploying a backup server with privilege separation^]
+* https://sysadministrivia.com/news/howto-grubrescue[Booting a rescue ISO directly from GRUB^]
+
+However, I do have a lot of Python (and some Bash) written. Examples include:
+
+* https://github.com/johnnybubonic/BDisk[A liveCD/liveUSB/iPXE image creator^] (in the process of a rewrite)
+* https://github.com/johnnybubonic/aif-ng[A preseed/Kickstart-like facility for Arch Linux^] (in the process of a rewrite)
+* https://github.com/johnnybubonic/vaultpass[A compatability wrapper between "Pass" password manager and Hashicorp's Vault^]
+(in progress)
+* https://github.com/johnnybubonic/OpTools[A collection of miscellaneous tools^]
+
+Please note that I only use GitHub for mirroring of select repositories; a full collection of all of my public
+repositories can be found https://git.square-r00t.net/[here ^].
