Video and slides synchronized, mp3 and slide download available at URL http://bit.ly/17Fdz9X. Stephen Hardisty presents how Etsy delivers products without having project managers, business analysts, or testers. Filmed at qconnewyork.com. Stephen Hardisty is an engineering manager at Etsy in Brooklyn. During a 15 year career, he has worked for both multinationals and startups in telecommunications, security and web. Although recent years have been spent helping engineers to build web products, Stephen still loves to code and will ruin any good party by telling people why developers should do less programming.
