Experience
Rentalroost
Built a recommendation engine for finding apartments, using Facebook likes and data, and calculating various neighborhood scores like pedestrian friendliness, pet friendliness, school ratings, demographic snapshots, shopping scores, arts and culture scores, etc. Source data is employed to make it easy for the user to choose an apartment. I have also worked on a feature where landlords can fetch the probable tenant's credit reports and criminal history (if any) to ease the process of verifying the tenants' dossier and making an informed decision (http://bit.ly/1PggefC).
Grayroost
Grayroost serves as a platform for apartment listing from various MLS boards in CA. I worked on extending the website to Massachusetts. Also, I built the logic that helps estimate the price of a property based on neighborhood market analysis and apartment input.
Addresses.io
Addresses.io is a B2B product for performance marketing and web analytics businesses. It provides clients with a service for verifying addresses, auto-suggesting addresses, and fetching geolocation. It also serves the client with various financial scores extracted from IP addresses, which helps them in targeting their user with increased efficiency. I built the product from scratch using Node.js for the back-end and Spring 2.0 for consuming the web service.
GymFlash
Gymflash is a community of fitness studios, instructors, personal trainers, wellness counselors, and fitness hobbyists. It provides a platform for users to connect with trainers, join gyms, and book classes/events related to fitness. Gyms and instructors can join as partners and showcase their events. I built the platform from scratch using Ruby on Rails.
TestPrecision
TestPrecision is an adaptive learning tool which helps students score better in their SATs and ACTs using predictive analytics. The app can dynamically predict the student's expected performance on tests as well as point out deficiencies in the student's academic training. The app provides many sets of tests using which it can predict the scores and provide suggestions. I have worked on the back-end and used Spring 2.0 for the web service.
