We have more than 12 years of programming experience. I have a M.S. degree in Computer Science (Major in Natural Language Processing) from Columbia University in New York. I have been programming for last 12 years working on wide array of products. Started a company in US and grew it to 25,000 developers (it's a website like Github). I have worked with various technologies - Mobile (iOS/Android), Python, Java, Javascript, AWS, Ruby on Rails etc. I worked at a company in New York, there I built search engine (based on Lucene, Solr) and built recommendation systems from scratch. I have published paper and posters in education data mining conference.
