Constantin Tambrea has been a senior software engineer at Luxoft Romania for more than 9 years, and has been involved in various projects in the telecommunications field. He holds master's and bachelor's degrees in Computer Science from University Politehnica in Bucharest. His main domains of interest are Java Enterprise applications and web development techniques, but recently he has become passionate about the Internet of Things domain, in which he is experimenting with a personal home automation project.

I would like to give thanks to Catalin Batrinu, my colleague, and friend, for introducing me to the IoT world and for encouraging me to review his work on this book.
