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).

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 know the developer's mind. Back in my developer days, I've worked with a lot of different programming languages and technologies.

I ran sessions at several international Scrum Gatherings and at all editions of Agile Brazil and Agile Trends BrazilI was the organizer of the Agile Tour 2010 - Rio de Janeiro.
