About

I'm an experienced web developer, passionate about coding. I enjoy working both with front-end and back-end development. I'm constantly learning new things and trying to improve myself professionally. I'm an adept of Agile methodologies, automated tests and Continuous Integration tools. I'm also known for disseminating Agile practices, such as Test Driven Development, Continuous Deployment & Delivery. I’m always eager to learn new things and to share what I have learned. Java and Javascript are the languages I am most experienced with, but I'm always willing to learn something new. At the start of 2018 I started teaching programming and good practices about software development to students who are starting their careers in IT in a trainee program. One of my favorites hobbies is go to tech events, I really like to talk with other about how to solve a problem in different ways, chance experience and meet people. I also occasionally participate in the professional community as a speaker.
