Add my new role on the NetBSD Foundation board.

That's enough to force merging "Volunteer Roles" and "Professional
Roles" into a single "Experience" section.
React to recent-ish feedback from Nathan and Abba:

* [Already got rid of "Volunteer Roles" in previous commit]
* Reword professional statement to be less dense.
* Slide my name and email left a bit to align with rightmost work years
* Remove "introductory" from CWRU coursework (misleading nowadays).
* Call humans "people" and their business "goals"
* Pair "constructively" instead of "kindly" (even though I meant that)
* Sort code skills into a more cohesive sequence
* Sort music compositions by year
* Sort bad poems by winningness
