This is a very revolutionary project. I did as an employee at Coderockr. Basically 2 month deadline, envolving basically 4 ~ 5 people developer. I was responsible for the app at Android (100%) and the web development almost 80%. The project envolves a lot of new technologies, such as AngularJS standalone clients comunnication though CORS with the server. This decouple of clients and server was need because the project envolves 3 different clients from the beggining (Android, iOS and Web). The Android application envolve a lot of corporal sponsored open-source projects such as EventBus, Retrofit, Picasso, ButterKnife, and others.

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.
