This app was done, and still maintained for a small startup hosted in Joinville. Really cool customer to have, trying to succeed in the voracious world of startup. But this is not frightening for them, they are looking for big investors and this should be promising. We did a lot of tricks with Android to achieve this, such as listen for calls, SMS's and web data, synchronize all that into our server, and then, provide rich information for the user.
Here you can find some nice comments from collegues 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.
