I would like to thank all the people who have inspired, supported, and encouraged me through the book writing process. For me, this book represents the ability to take my passion to build software, my appreciation of the Spring family of frameworks and the amazing work that was done by their creators, combine it with many years of my first-hand experience building complex applications and share all the thoughts and best practices, which I've developed over time and always wanted to share, with the community, to help them build better, more elegant, robust, and performant applications.

I want to specially thank my wife, Alla, for constantly being there for me, for supporting me in writing this book, for being understanding when I spent countless evenings and weekends working on the chapters, for giving me an extra push to the finish line, when I was close to being done and for just being there for me! Honey, I love you very much!!!

A special thank you goes to my parents, for giving me the opportunity to pursue my carrier dreams, for the education, and raising me to become the person I am. All your hard work is now paying off, and I would not be able to achieve what I had, and write this book, if it weren't for you. I love you guys a lot, and while you are around, I can still be a child.
