Motivation is the first word it comes to my mind when we speak about Xavier.
Despite coming from a total different background, he has been able to learn in very few time the current technologies we use and the different business processes we run.
Xavi is always trying to learn more and more about any technology or business issue in the company.
He also have a great disposition to listen, and receive tips and recommendations on how to improve, processes, decisions and self management.
Finally I would like to remark the good person he is, with a lot of soft skills that helps to develop a good working environment with any teammate.

Conocí a Xavier gracias a la web de superprof y la verdad que no podría estar más satisfecho. En cuanto a conocimientos matemáticos sabe muchísimo y además sabe como explicarlos para que se entiendan mejor, elemento fundamental para un profesor de mates. Siempre está dispuesto a hacer clases e incluso a resolver dudas urgentes por teléfono. Además es muy organizado y sabe cómo sacar el máximo de sus alumnos. Muy recomendable.
