On the Site Reliability Engineering team, we support a large AWS infrastructure that sends billions of emails a month on behalf of our customers. I write tools, automate repetitive processes, troubleshoot issues and perform on-call duties. Much of my work revolves around Circonus and their REST API, also Boto3, Python and AWS CLI.

When I was in DevOps I supported Software Engineers in a fast growth Cloud Services company. Managed a large-ish OpenStack cluster and hundreds of VM's. Consolidated, upgraded, and stabilized the OpenStack controller and hypervisors, implemented disaster management and fault mitigation, backup, DNS migration and Icinga monitoring. Trouble-shooting Atlassian tool chain, Bamboo build issues, wrote runbooks, procedures and Confluence documentation.

Sensor and actuator coding on embedded Linux and CAN bus. Integrated Delphi ACC IV radar with Autonomous Mobility code. Stripped down Linux to a minimal RT kernel and services.

It started with fixing Eclipse Pango errors for our embedded developers on Solaris. Then installing (easy) and configuring (not so easy) Fedora (now 389) LDAP on Red Hat Ent 4 x86_64 integrated with AD. The next thing I knew I was gathering up servers from under desks, in closets, an on bookshelves and wrangling with Facilities to bust out closet walls and create a proper climate controlled data center. In the end I had 50 servers, 2 A/C's, 208V UPS's, HP blades, a growing SAN, two tape robots, a layer 3 switched Cisco network backbone, a direct report and one Intern per Summer.With IT overloaded serving over 500 employees and contractors in a DoD environment, I set up Drupal, Jabber/XMPP, Mercurial, and other programmer-friendly collaboration services behind Untangle, trying to provide a modern work environment for our extremely engineer-heavy crew.

vxWorks , 80186 Tasking C and embedded Linux coding, JAUS messaging, primarily A2D sensors and actuators and the occasional blinking LED. Wrote control software for M56 smoke generator. Getting a balky HMMWV automatic transmission to shift via robotic actuator, with minimal and slow feedback was a highlight- managing hysteresis was key here.

I did RFC level C++ RADIUS and SNMP programming for AAA and monitoring 1.5million modem, 60,000 NAS, 10,000 Router network. The data resulted in millions of dollars per month of billing. I carried a pager. Our customers were every ISP you ever heard of and most you didn't. GTE spun us off into Genuity Inc., we had a huge IPO, and then we went bankrupt.Genuity was publicly known for its "Black Rocket" commercials, a pre-provisioned web services venture out of Massachusetts that lost a lot of money and was never 1/10 the size of dial up services that paid the bills. But they really went bust spending 7 Billion dollars on a nationwide backbone network that nobody needed, and was more expensive then the lines we were renting from MCI. If you bought dark fiber on the cheap in the mid-2000's, thank Genuity.Every year we built out a dial-up network we knew would be obsolete before we finished it, as DSL and Cable Modems were arriving. I worked there two and 3/4 years. I knew it couldn't last, and it didn't. It was a classic dotBomb.

Buildmeister and programmer on the Landsat 7 high fidelity satellite simulator project. Responsible for payload simulation in multithreaded C++. This simulator was used to verify actual flight software (1750A CPU emulation), test flight manoeuvres and train the flight operations team.Lead a tiger team to resurrect software development on the SOHO simulator and push through Flight Software changes to test emergency spacecraft recovery (ESR) procedures. We got it done on time and had a role in verifying the new flight simulator code and recovering the spacecraft.

Webmaster (one of several) at NASA's library, back in the day when we debated if using a JPEG over a GIF was inconsiderate due to bandwidth considerations! haha. SunOS and AIX web servers and full text search. Remember Gopher?CSC took over the contract and called me and wanted me to come back because I actually DOCUMENTED what I did there. The transition was not handled very smoothly, as I got the offer for continuance a few days before the turnover and a few months after my layoff notice- I had already moved on.
