To my parents, Céu and Manuel, and sister, Joana, who always gave everything they could and more to ensure my education, happiness and well-being. To my partner, Joana, for all the love, support and unbelievable patience while I was writing the book. To my friend, Carlos, for all the support and understanding every time I told him I didn’t have the time to help him with GDG and Kotlin Knights events. And finally, to the amazing Android devs from my team at Mindera - Maja, Rita, Garcês, Belchi and Gui - for all the incredible discussions, for teaching me so much and for making me love what I do even more.
