Research Projects Sybil Detection using Crowd-sourcing January 2012 to May 2012  Worked on Sybil (fake accounts in social networks) detection system using crowdsourcing.  Conducted large user-study to evaluate human ability to identify fake accounts.  Proposed an accurate and scalable system that combines human intelligence with automated tools for Sybil detection. Uncover the Evil Online Crowd-sourcing Systems September 2011 to December 2011  Study and measure evil crowd-sourcing systems where internet users are organized to perform malicious tasks such as creating and spreading spam in social networks, posting fake reviews, fake account registration, etc.  In the proceedings of WWW2012 Conference. Academic Projects Mixed Consistency Model in NoSQL Datastore  Idea is to execute strong consistent writes in an environment where majority follows eventual consistency.  Developed a wrapper on top of LevelDB that allows consistency level(strong or eventual) to be determined on a per request basis.  Learnt and used RabbitMQ messaging service and Zookeeper’s distributed locking service. Scalable Web Application: BookSmart  Developed a platform to buy/sell/rent book on peer-to-peer model, with live comparison of Amazon price for the same.  Learnt various scalability and optimization techniques for web based application.  Allowing a provision to refine book search based on the proximity to book owner using Google Maps API. All Pair Document Similarity Search  Learnt Hadoop MapReduce framework to process large scale data.  Computed all pair document similarity score using scoring models used by search engine and evaluated using clustering techniques. Encrypted File System on Key-value store  Developed an encrypted file system in user space on top of Berkeley DB – embedded database for key-value data.  Learnt about file system design and implementation, encryption techniques. Search and Archival Service for Online Social Networks  Web service that allows users to backup and search their content from various social networks like Twitter, Facebook, Google+.  Learnt about working with different social network API’s and using Sphinx – an open source search engine. Work Experience Software Engineering Intern, Appfolio Inc., Goleta, California June 2012 to September 2012  Part of the development team of Appfolio SecureDocs: Secure virtual data rooms for corporate archiving.  Implemented support for two factor authentication for international users with Telesign as carrier.  Technologies learnt include Ruby on Rails, MongoDB, Test driven development with unit, functional and selenium testing. Software Intern, Goldman Sachs, Bangalore, India February 2011 to July 2011  Developed an application to keep track of the server orders placed across organization using JavsServerFaces.
