Ricardo is an Android dev with a crush on clean code and software architecture. He currently lives in the city of Coimbra, Portugal, and works as a senior Android engineer at Mindera, where he works on a retailer app. Ricardo loves Android and the community, so it’s only natural that he tries to have an active part in it! He’s a co-organizer of GDG Coimbra, a co-founder of a group called Kotlin Knights, and occasionally writes (mostly about Android) either at his site, ricardocosteira.com, or for Ray Wenderlich. He loves cats, food, the gym and is a specialty coffee hobbyist. You can find him on Twitter at @rcosteira79.
