About the Reviewers

Marco Ferreira was born in Lisbon, Portugal, on February 28, 1984. He likes traveling, biking, beaches, and warm weather. After living in Portugal and the Netherlands, he now lives in Santa Catarina in southern Brazil.

The first big project for Marco started when he joined one of the biggest ISPs from Portugal (currently known as NOS). There, he and his project colleague created the backbone of the ISP's voice service.

Seeking financial freedom and schedule flexibility, on April 20, 2010, Marco started his own development business as a freelancer. This was when he started exploring Appcelerator Titanium, as it would give him a big head start in offering mobile development services.

He is one of the four founders of Altitude, a company based in San Francisco that is creating the next generation of identity. As the CTO of the company, he has architected all the details of the company platform, written of a lot of source code, and managed development teams.

I would like to thank my beautiful wife for all the support she gives me, and my company's fellow founders and friends for pushing the boundaries of my skill set every day.
