Career Profile

I'm a Javascript & Node enthusiast, I’ve worked as software developer/tech lead for more than 10 years. In those years I've been working in some different technologies like Javascript(both client and server), Ruby on Rails, MySQL, Redis, React, Redux, Grunt… I love creating new things, learn new technologies. But one of the most important thing is that I'm a team player and I love to cooperate with other people to achieve bigger goals.

I strongly believe in agile methodologies, for me was a game changer because as digital product developers this methodologies help us to add value to our products and give us the possibility to know if our assumptions were correct or not faster and let us change our approach if needed. In the last years due to the needs of the team I work as Tech Lead and other roles (PO and Scrum master) in a temporary way until new people joined the team so I have experience from different points of view about this methodologies.

Some years ago I realised that besides being an individual contributor I also like to manage people and try to build cooperative and cohesive teams and push them up to the next level. I helped to build a multidisciplinar team (around 20 people), helping them to grow and work in a cooperative way and trying to help them to avoid to work in a crazy atmosphere, and achieving that is one of the things that make me proud.

In my spare time, I try to do different pet projects to learn new technologies and building products, like Organizestaging where I learned a little bit of React Native, or make an Alexa skill to read news just to know more about virtual assistants. Also I try to assist to different events to share my experiences with the community.
