João Paulo
I have been working for now more than 5 years with mobile and web development, plannning e executing complex solutions for a variety of business types. I am fueled by the daily life challenges as a programmer.
From Brazil, I have always been interested and pushed into the tech world since I was a little kid, and my affinity with coding solutions is way beyond just lines of code!
I have a good amount of hobbies, and among the main ones is my passion for expressing myself through music, always seeking for learning new things.
