First and foremost, I would like to thank my four mothers for the values, love, and inspiration I got from them every moment of my life. I also wish to express my sincere gratitude to Shivani Wala for providing me an opportunity to be part of this great project. At the same time my special thanks to Michelle Quadros for keeping me updated with the deadlines and any doubt I had. Last but not least I wish to avail myself of this opportunity, express a sense of gratitude and love to my relatives, professors, and friends.

Javier de la Rosa is a full-stack Python developer since 2005, when he first met the Django web framework. During his years in Yaco, one of the main FLOSS-based companies in Spain, he leaded the Research and Development Team, participating in both European and national projects. Late in 2009, he started to collaborate with The CulturePlex Lab for Cultural Networks research, at the Western Unviersity in Canada, in his sparse time. As a result, he left Yaco in 2010 and joined the laboratory to lead and supervise technical and software developments. Today, he is still in charge of the developers team as well as conducting his own research on Big Culture, where he mixes his background as a BA and MA in Computer Sciences, Logics and Artificial Intelligence by the University of Seville, and his recent acquired skills as a 3rd year PhD student in Hispanic Studies at Western University in Canada. Currently, he just started his 1st year as a PhD in Computer Sciences, focusing on Graph Databases and Query Languages.

A regular collaborator of Open Source projects, he is the owner and main developer of qbe (http://versae.github.io/qbe/) and neo4j-rest-client (https://github.com/versae/neo4j-rest-client).
