About the Reviewers

Simone Carletti has been working professionally with Ruby since 2006. He's very passionate about code quality and best practices.

He has been involved with free and open source software (FOSS) for more than a decade, contributing code and creating libraries in several different programming languages. The most recent projects are available in his GitHub account (weppos).

Currently, he is working as a Software Developer at DNSimple—a company providing DNS hosting, domain registration, and SSL certificates. His personal website is http://www.simonecarletti.com/.

Sergio Tulentsev is an early MongoDB adopter and Mongoid fan. He has used them to build systems that handle substantial load (greater than 100 million hits per day). He often speaks about MongoDB at conferences and even patched it once or twice.

When not fending off bears in snowy Russia, he travels, tries new kinds of food, and learns new languages.
