Javier has been focused on optimizing the Web for over a decade, working with the largest Companies who are changing the world to ensure the Web is fast and secure for everybody. On this inspiring talk Javier will explain how this quest for optimizing everything expanded from his work, to other areas of his life like beating all computer games high scores, getting waves on a highly competitive Hawaii, and reducing a long bike commute from 3 hours to just 54 minutes; and how those principles apply to Web Performance.
