Specialties: web testing, UI automation, watir, winrunner, manual testing, automated testing, working with offshore resources, perforce, ruby, windows, mac, unix I’m an experienced Software Test Engineer with an emphasis on UI Test Automation. I have worked for AdXpose (acquired by ComScore in 2011), Zillow and Microsoft Game Studios. I am a good manual tester but my best work has been with automated test systems for web browsers. I completely rewrote Zillow’s UI test automation for WinRunner, then built a whole new test framework from scratch in Ruby using Watir. I made enormous improvements in efficiency, reporting, coverage, and stability. I’ve also used these and similar skills for jobs like scraping public databases. I will also mention that I have coding skills, and I have used those to develop some tools for my own use as a musician. I’ve coded in C++, C, Ruby, Perl, Python, SuperCollider. You may notice a gap in my employment history – I was supporting myself as a musician during that time. I attained a degree in Computer Science from Carnegie Mellon University. I’m a quick study & always ready to pick up new skills and apply them on the job. Finally, I will mention that I have a professional and positive attitude and great communication skills.
