Alessandro Colla is an eCommerce specialist a C# programmer and a Domain Driven Design expert. Over the course of now thirty years in IT, he has developed software for management systems, and ERPs, from scratch for a wide variety of fields and helped teams in their learning and improvement. He is also the co-author of ""Cronache di Domain-Driven Design"" and co-founder of ""DDD Open"" and ""Polenta and Deploy"". Alberto Acerbis is basically an eternal student because the subject matter is endless. He has always defined himself as a backend developer, but he does not disdain poking around on the other side of the code either. He likes to think that 'writing' software is mainly about solving business problems and providing value to the customer, and in this, he finds DDD patterns a great help. I am a co-founder of the DDD Open and Polenta and Deploy communities.
