A great project to be part of, contracted by Humantech to make this calculator that though some measures can provide the user how much of a product he will need, really useful to users. This new version got a better UX and follow patterns better. Available to iOS and Android, I have done both :)
Here you can find some nice comments from colleagues I have been working close across the years.
Guilherme is not only a very carefully and fast learning software engineer. Besides being able to adopt very quickly to new software components, languages, and patterns, he was also an outstanding team colleague. His sharp mind, gentleness and willing to always improve make Guilherme a very valuable team member. I would be very proud if I had the chance to work with him again.
For the past five years, I have been working with Guilherme. Since then, I have gotten to know Guilherme quite well and can thoroughly vouch for his character, professionalism and technical abilities. I have worked with him on close to 15 different IT projects, and I have been constantly impressed with both his technical skills and performance in our field.
