I am a Senior Software Engineer at SnagFilms, Inc. In school I obtained Masters in Computer Science from Indiana University. Then I worked for the Cyberinfrastructure Network Science Center where I built tools for large scale network analysis, and modeling and visualizing information in Bio-medical, Social Science and Physics domain. Over there I also led the efforts for developing visualizations for VIVO – a web-based application for facilitating the discovery of researchers and collaborators across the country. Then I worked for General Sentiment where I worked as a Web Applications Team Lead, Engineer, Project Manager and led complete reboot of the site with completely new public facing website, over 5 new paid web applications, revamped admin site, improved uptime of the site from 99.85% TO 99.97% & reduced average response time of the site by over 85%.

Being part of the Social Network development group in VIVO, I along with my colleagues have designed & developed visualization architecture which makes it relatively easy for third-party developers to drop in their visualizations & start leveraging the power of VIVO’s semantic data backend. In the past I have worked on the sparklines, ego-centric & temporal graph visualizations which were part of the recent VIVO release. Last my focus was to develop a caching framework to make our heavy-duty visualizations like temporal graph to be snappier.
