Bio

I'm a Web Developer for ~15 years, and during the last 6 years I have been working in several SPA and PWA projects in a big diversity of frameworks, such as Backbone, React and mainly Angular (1.x and 2+), which gave me a rich FrontEnd experience. I have always been close to the BackEnd as well in several platforms, such as NodeJS, Java and .NET, although FrontEnd and JavaScript will always be my preference. I am involved with IT and Open Source communities for a few years, where I began to share my knowledge in talks, organizing meetups and conference tracks.
