Senior Site Reliability Engineer

LinkedIn

Left the great white north, to take up residence in the South Bay area of California. At LinkedIn one of the main goals of the SRE is to "Keep the site up" and ensure services respond in a timely manner (measured in milliseconds). I am building infrastructure that supports the LinkedIn recommendations infrastructure. For example "People You May Know", "Jobs You May Be Interested In" and such.

Systems Engineer - Lawful Access Systems

BlackBerry (aka Research In Motion)

Read "Lawful Access" summary from the BlackBerry legal team.

Stepped away from a people leadership role to assume a position as an individual contributor within the BlackBerry Lawful Access organization. As the name suggests, time was spent interfacing with law enforcement, government, military and regulatory agencies. We had a clear mission with an open slate as to how we could design our infrastructure. Network intensive applications developed in C/C++ were deployed across the RedHat platform, with tools such as SaltStack, Ansible and Graphite for the monitoring and metrics side. Internal tooling was written in Python, making use of libraries such as Scappy, Bottle, Django and Construct.
