Company Overview

Lookout was my first job in the SF Bay Area. They provided a mobile security application that used various techniques to detect malware or risk on apple and android products, including by running applications and looking for runtime signatures of malware as well as performing static analysis of the source and binaries, within the constraints of the google and apple technology platforms and app stores.

Lookout exposed me to automated environment creation including dev environments with vagrant and docker as well as the culture of startups in the Bay.

Project: Test Automation

With my experience at Progressive Insurance where I had learned to build my own code instrumentor for dynamic analysis, which I used alongside existing static analysis tools to test and measure deployed systems, I had a rich understanding of how to analyze runtimes of mobile apps, which was part of Lookout's mobile security backend special sauce.

With this mutual interest in mind I joined and helped create and standardize automated test suites as an engineer, developing libraries, frameworks and declarative jobs that constituted the types of tests needed to assure correctness and security of our own software offerings.
