product and AI engineer with a lot of experience and passion about Natural
Language Processing, Computational Linguistics and software engineering,
who always try to create digital experiences that are both beautiful and
useful. My mission is to build systems that help and delight users.
I have always supported the idea of Robert Venturi about maximixalism,
“Less is a bore.”, however I try to build digital experiences that helps
people instead of `just` being a beautiful piece of art.
I'm also a true believer of the idea that the best way to learn is by teaching,
the best way to improve something is allowing others to criticize it, and the best way
to grow is by helping others grow. (AKA, design beautiful OpenAPIs and allow other to build on top of your products)
In my spare time, I love to
listen to
and
play
neo-jazz instrumentals on the violin, cook (sometimes), go on
long walks and take
nature pictures.
