Freelance web developer specialized in mobile web, HTML5, javascript and cross-platform applications with PhoneGap, Sencha Touch, jQuery mobile, Angular.js, Node.js


Thanks to the storage API and HTML5 application cache, using your application without an internet connection is a formality. The application is synchronized as soon as the connection is found.


The HTML5 geolocation API allows you to easily locate, once or continuously, the device on which the application is used, with the same accuracy (GPS) as a native application.


Code once, run anywhere with PhoneGap or React Native, no need to develop different applications for Android, iOS, Blackberry, Windows Phone, etc.


LinkedIn, Facebook, Google, Tumblr, Basecamp, many large companies use web applications made with PhoneGap or React. As fast as native applications.
