About Me

Aleix Balletbó

Hi there 👋! I'm Aleix Balletbó, software & data engineer and technology enthusiast.

I'm specialized in data technologies, and I've been working the last years in Big Data projects. However, I'm passionate about all the fields related to software engineering, and I have experience developing projects for mobile, web and videogames.

I believe that a strong knowledge of software architecture and best practices, combined with agile methodologies and a product mindset are the key principles to achieve the best possible outcome and deliver value that makes a diference.
