For Julie, Sofia, Eva, and Angelo

you are life and joy

I may have pushed a lot of buttons on keyboards to write this book, but I owe its fruition to the efforts of so many others. A whole lot of thank yous are in order.

To my Heavenly Father for life, my savior Jesus Christ for hope, and the Holy Ghost for peace. Thank You for rescuing a soul so rebellious and proud as mine, and may I live a life that extends to all others the love and grace Youve extended to me.

To Mom and Dad, thank you for all the lessons youve taught me. To my brother Denis, I couldnt imagine how a brother could have done a better job than you did.

To my friends and coworkers who have had to endure me talking about this for 2+ years. We can finally have a meeting where I dont bring up my book.

To Adrian Bilauca, Damien Del Russo, Dave Copeland, Ben Marx, and Adam Jasiura for being technical reviewers of this book. You gave of your time and expertise with no expectation of reward. When I compare the early drafts to what your feedback guided me to, well, thats why books go out to reviewers. You delivered, and I and all the readers are in your debt.

To Jesse Riggins, for being a technical reviewer, a friend, and a fellow learner of microservices-based architectures through the years. Its been wonderful bouncing ideas off you, and goodness, I hope we get to work together again!

To Scott Bellware and Nathan Ladd, I have met few people as knowledgeable and as generous as you both. Thank you for the work you do in the Eventide community and in our profession. Scott, it was pure serendipity that led me to a TDD talk of yours at the LoneStarRuby Conference, a talk that permanently altered how I approach software development. Nathan, Ive never had the pleasure of meeting you in person, and Im so glad you made it. I aspire to become as good at my craft as you both are.

To Todd Pickell, thank you for taking that phone call that one day and telling me to go speak at meetups. You probably had other things to do, and I truly appreciate that gift of your time.

To Brian MacDonald, thank you for coming to OpenWest in 2017, staying to talk to me after that session, and encouraging me to write a pitch. I had no idea what an amazing and life-changing ride this would become.

To my editor, Adaobi Obi Tulton, the highest thanks are in order. I dont have the hubris to claim that Ive been the most difficult author youve ever worked with, but Im certain youve had easier projects. You are excellent at what you do, and if this book provides value to its readers, I dont think it would have without your excellent guidance. Thank you for talking me down from the ledge of discouragement, and thank you for saving this text from my attempts to be clever. Readers, if any of you ends up writing your own book for PragProg, ask for Adaobi!

To my dear children, Sofia, Eva, and Angelo, this book has cost a lot of memories of playing together that we might have otherwise had. Thank you for bearing with me and even being excited about this project. Its finally done! You are three of the most wonderful human beings I have ever met. It is an honor to know you and a blessing beyond words to get to be your father. Your imaginations and sense of wonder remind me constantly of how great a gift each day is. I love you, and I couldnt be prouder of you. Now lets go play!
