Senior Engineer

Created a small company with 8 people from Linaro. I am the owner of the Continuous Integration and Device Management products and all other back-end services for the company. This lead me to create JobServ, a highly available and scalable open source CI engine. I also created a couple dozen Kubernetes deployments running in Google's Kubernetes Engine. Other notable accomplishments include:

• Contributing to several components of the OTA Connect project as well as creating blog series on making production deployments into GKE.
• Creating a multi-architecture enabled Docker registry with Notary enabled detailed version-to-version vulnerability scans and changelogs.
• Developed some novel new ways to do bare-metal testing for embedded Linux devices as well as Zephy-class microcontrollers.
• Contributing both Docker App and "aktualizr-lite" support to the Aktualizr project.

Linaro 2013 - 2017

Senior Engineer

Ran a small team of three engineers reporting to the Director of Engineering. The team was tasked with developing and maintaining all of Linaro's internal tooling such as Jenkins, Git and Gerrit. Notable accomplishments include:

• Added Python bindings and a board-probing mechanism for determining GPIO pin mappings at runtime to libsoc.
• Updating Linaro's Git service, git.linaro.org, to be high-available and horizontally scalable.
• Upstreaming a REST API into the Patchwork project and helped review the patches for "series support". Patchwork is an important tool to many key kernel maintainers for managing their incoming reviews. Its also used by Linaro to help understand what areas such a large organization is actually working on.
• Creating the reference architecture for deploying one of the world's first OpenStack deployments on ARM hardware. This turned into the Linaro Cloud.
