Hi! My name is Rafael Sabbagh and I'm an Agile coach and trainer. I offer training and coaching to people and companies from all over the world through my company, Knowledge21. I am a Certified Scrum Trainer (CST) and a member of the Scrum Alliance Board of Directors.

My classes are higly interactive and student-centered. This way, I intend to give my students a real experience of learning and create an environment of experience sharing. 

My background includes about two decades working with IT projects and leadership of development teams. I worked as a ScrumMaster and today I work as an Agile coach in companies of different sizes and I teach Agile and Scrum in courses, events and organizations.

I'm a Computer Engineer and Master in Business Administration from the Pontifical Catholic University of Rio de Janeiro (PUC-Rio), Brazil. I am an experienced software developer and I've worked in the past with several different programming languages and technologies.

I ran sessions at several international Scrum Gatherings and at most editions of Agile Brazil and Agile Trends Brazil. I was one of the organizers of Scrum Gathering Rio de Janeiro 2014.
