Nevertheless, I have always been in love with front-end.
For some time now, I have also decided to focus on mobile. I wrote my first mobile site nearly a decade ago using WML for WAP networks (if you are young, you may need Wikipedia to understand the previous sentence). Imagine my excitement that arose later when we entered this new era of smartphones and what they mean for the Web. I strongly believe the Web’s uniqueness lies in its offering a democratic and universal platform.
I have already worked at some companies, programming in various languages (I even made some money with opensource). Since 2004, I have worked at Caelum as an instructor and developer. That is where my career took off and where I learned the most and continue to learn every day. It is also where I intend to spend many, many years to come.
Teaching and writing have been my passions since high school. I remember the disappointment of my Portuguese teacher when she discovered that I had chosen a career in the exact sciences. Yet teaching, writing articles, blogging, and lecturing are my ways of blending these skills.
This book is the high point of this whole trajectory. I hope it is as fun for you to read as it was for me to write. Thank you for believing in it and buying it.
You can also find me writing out there on the Web, mostly in Portuguese:
If we meet someday at any event, be sure to call me so that we can have a nice chat.
