Transcript

Hi, my name is Erica Gomez and I'm an engineering manager at Amazon.com. One of the best things about working in tech, and at Amazon in particular, is that I get to bring my dog with me to work every day. My job is to help make sure software gets out the door and her job is to nap under my desk and snore very loudly. My name is Jerome Holman, and I... Read More
