I am a cross-platform development enthusiast thrilled by the opportunities offered by modern web technologies: I help enterprises and independent software vendors to develop modern, cross-platform business applications based on Angular.

Being a Microsoft MVP and Google GDE, I speak about Progressive Web Apps at user groups and conferences, both national and international. As a member of the W3C WebApps working group, I help to move the web forward.
