Murillo Wolf
I solve problems with beautiful design, good code and some coffee.
My goal is to build products that are not only functional but also a joy to use.
Keep it simple
I believe that technologies should be make life easier, not harder. Sometimes we get so caught up in the latest trends and buzzwords that we forget the most important thing: the user.
Maybe I don't chase the flashiest trends, but I do ship the most useful solutions.
Projects that I'm proud of
For me share is the best way to help others and learn at the same time.
That is why I open source almost all of my projects.
