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. .
