    Martín Acosta

    Web Senior Developer with new technologies

    Argentina - Last active: 22 days ago - Tests: 1 - Portfolio: 2

    I'm an ambitious JavaScript developer with a strong technical background who possesses self-discipline, the ability to work with the minimum of supervision and to play a key role throughout the software development. As JavaScript Senior Developer my experience consist in five years working with different technologies and methodologies in the JS ecosystem. In my first years i worked with AngularJS and jQuery to create single-page applications using always a PHP backend. But with the pass of the years I realized that create great and powerfull applications don't need to have a big framework inside (e.g AngularJS). So in my last years i had the oportunity to work in proyects directed by me and where i could work with minimalistic libraries and with a strong philosophy based on modular/components web applications. So in the present i'm working with beautifull and powerfull technologies such as: - VanillaJS - MithrilJS - Browserify with Babel - PostCSS - Gulp - VelocityJS - Meteor - Node.js and io.js - HapiJS - MongoDB - Cordova - Crosswalk Project My objective is create applications where the client/user has the best experience. Where the client UI and the server side has a similar and shared environment to work, a unix like philosophy based on modular/components applications. My weaknesses as you maybe know at this moment is my poor english, but i'm trying to improve that part of my education.
