“Software decays. Martin Fowler tells us that debt is inevitable. Even with the cleanest code in the world and the tightest dev practices and methodologies, technological change will still outpace you. The app you're working on today is already out of date.

From the heart of the systems that provide massively scaling services for Olympic ticketing, to the cutting edge mobile technology that lets you choose the best seats, we'll discover how we got the right data to the right people to get maintenance on the map.”
