  • Trulia Real Estate App (Development)

    Trulia is part of Zillow Group—the biggest real estate search provider in the United States. One of my roles was writing the automation for our main Android app.

    We initially used Appium for automation, but then switched to Espresso for the stability and speed increases. The app had millions of users and repeatedly won the "Editor's Choice" award in the Google Play Store.

  • Trulia Website (Development)

    One of my other responsibilities at Trulia (Zillow Group) was to migrate our Selenium Java tests over to Cypress JavaScript tests. This greatly increased both the speed and stability of the tests. I also spent a few months wearing the hat of a junior developer, contributing small updates and bug fixes for our main website.

    My nine-year career at TD Ameritrade started with my role as the first QA engineer at a startup called Prophet Finance.

Our QA team for the charting platform eventually grew to six people, where I led a team of four offshore testers.
