20+ years ago I started my IT career as a Java developer and have moved from consulting into hands on technical leadership at a product company. I've witnessed first hand REA's platform journey as we made a series of deliberate and sometimes less deliberate decisions to try and streamline delivery through platforms (and other means). Our story feels quite relevant for PlatformCon as the challenges of scaling from a handful of systems to over a thousand, from tens of developer to hundreds, from one office to multiple with an evolving platform would be quite common despite our Australian geography. As someone who has worked on many of these platforms (and replatforms) I'd like to help others with their journey.
