Marco Consolaro is a software craftsman, systems thinker, agile technical coach, entrepreneur, philosopher, and restless traveler all blended with Venetian humor. Marco learned to code in Basic on a Commodore when he was 9 years old. He graduated from Venice University in 2001 with a degree in Computer Science. Since then, Marco has worked in Italy and the UK and is always looking to learn something new. When his journey led him to the agile principles, he quickly realized the effectiveness of such an approach for both technical and organizational areas. He now strongly believes that an iterative approach based on trust, transparency, self-organization, and quick feedback loops is the key to success for any team in any discipline. His dream is to see these principles based on systems thinking understood and implemented at every level in businesses and public administrations. Follow Marco on Twitter at @consolondon.

Alessandro Di Gioia has helped a variety of companies (from small startups to large enterprises for the past 18 years) embrace agile technical practices. He has worked in Italy and Norway. For the past few years, he has resided in London. His professional life changed when he came across agile methodologies, especially Extreme Programming. He likes concise, expressive, and readable code as well as making existing solutions better when needed. He is always trying to learn better ways of designing asynchronous distributed architectures and crafting software, in either an object-oriented or functional style. Although Alessandro considers himself a forever learner, he is also a coach and a mentor because he loves to share his experiences with others. Follow Alessandro on Twitter at @Parajao.
