My name is Aaron McLean. I’ve worked at AT&T for 17 years as a web developer and architect. In fall 2014, our group was in need of high-quality, low-cost training and certification. While we had online training, we needed more specific certifications within our software-centric network environment. Then one day, an email was sent to us from John Donovan (our Chief Technology Officer at the time), asking us to check out Udacity.com.
