Associate Manager, Software Development Red Hat
I only discuss politics in person. Managing a group working on OpenStack for Red Hat. Married to Heather, father of Evelyn. Frustrated historian.

Self Introduction

My name is Nate, and I am a husband, father, and manager of a team of software developers. My wife and daughter are the lights of my life. I live in Sterling, a town in eastern Loudoun Country, Virginia.

I have been in the tech industry since I graduated from college in 1997. I have worn many hats: system administrator, software developer, software architect, SRE, and now manager. Mostly I have worked in the telecommunications sector, for such companies as MCI, Cable & Wireless, AOL, Comcast, and Red Hat.

I enjoy playing games - both board games and role playing games.

Getting Fired

 Recently I saw on Twitter a prompt to share your worst/most hilarious getting fired stories. I have a pretty good one from more than twenty years ago, so I figured I would write it down.
