When he was nine years old, little David Ostrovsky found a book in Russian entitled (in English) Electronic Computational Machines at the local library. After reading it cover-to-cover in a single weekend, he decided what he was going to do with his life. Three years later, he finally got to touch a computer for the first time and discovered that it was totally worth the wait. One thing led to another, and now he's a senior solutions architect at Couchbase. David is a software developer with more than 16 years of industry experience as a speaker, trainer, blogger, and coauthor of the book Pro Couchbase Server, published by Apress Media, and author of the Microsoft official courses "Essentials of Developing Windows Store Apps Using C#" and "Advanced Windows Store App Development Using C#" (20484, 20485). In addition, he has written numerous articles. He specializes in big data architecture and large-scale distributed systems.
