Paulo Barbeiro has been involved in digital world development since 1999 as a web designer. During the last 15 years, he has worked with frontend and backend web development, mobile apps, games, and electronic arts, and has taught creative code principles and techniques.

He graduated as a graphic designer, but digital environment development was always a passion, so the natural move was in the direction of computer science, specializing in game development and computer graphics. He believes that there is no border between artistic creation and logical thinking for software development—both elements must work together.

Being a Unity3D user since version 1, Paulo was thrilled to contribute to this book as a technical reviewer. He has also contributed to books about Panda3D by Packt Publishing.

Currently, Paulo resides in São Paulo, Brazil, working as a lead developer for the TicTaskDo mobile app and in SESC SP, organizing events and seminars about digital art, code, and interactive environments.
