Works with cross-functional partners in product development, technology operations, credit/risk, security, and product to deliver projects well – on time, without major issues, and covered by test automation.

  • Built test automation (Python, using RobotFramework and py.test for test frameworks) from ground up! We went from zero (and no automation team) to hundreds of tests running continuously (and a team of test automation professionals!)
  • Deployed infrastructure (Jenkins, Saucelabs) to enable on-demand, reliable test automation.
  • Worked with technology and infrastructure partners to design & implement testing and best-practices architecture for cloud-based products (Salesforce) and virtualized infrastructure (AWS, VMWare).
  • Owned cross-functional technology initiatives such as infrastructure deployment and critical legal changes.
  • Developed quality engineer practices and processes including test documentation, Agile testing, career development, and performance/stability testing.
  • Developed and implemented scalable processes for maintaining critical infrastructure. Lead a cross-functional engineer in efforts to deploy major security and infrastructure tools to a complex system (30+ apps) with no customer or user impacts.
  • Lead identification and short-term remediation of major production outages. After the dust settled, I worked with all parties to address structural issues through new development and process changes.
  • Designed and implemented release process (Change & Release Management) to minimize impact of regular deployments on business and customers.
