I hold a PhD in Computer Science, and MS and BS in Computer Engineering.
My background includes Data Mining/Web Mining, Multimedia and Information Retrieval, User Modeling, Recommendation Systems and Online Computational Advertising.
I have vastly worked with large data collections such as Flickr, Yahoo News, Yahoo Query and Web logs, and as well on Twitter data. I have also done various researches on credit card user's transactions, Sentiment Analysis with Yahoo and Yelp data, and geographic localization of images and videos.
My specialities are Apache Hadoop/PIG, Java, Python and R.
But I also like to make websites playing with HTML5, Javascript and CSS.
