I would like to thank my wife, Marylka, and my two boys, Wojtuś and Mati, for being patient and letting me finish the book. Without their help and understanding, this book would not have been possible.

I would like to thank all the people at Packt Publishing, especially Govindan K, Aman Preet Singh, Ellen Bishop, Richard Gall, and Sam Wood—you've made the entire writing and publishing process very smooth and straightforward. A special thanks to all the technical reviewers and proofreaders for providing me with valuable feedback from which I have learned a lot. Thank you.

Greetings to my friends at 7N, Nykredit, Kredyt Bank, and Bank BPS—I hope you enjoy reading the book as much as I enjoyed writing it.
