Experience
  • Showtime Mobile Content Management and Delivery System (Development)

    System content was imported using XML feeds from content partners. Subscribers were able to directly download music from mobile phones using a WAP/GPRS connection. The system included some statistical, customer care, and manual content management interfaces. The entire system was developed using Ruby on Rails and PostgreSQL as a database. The system was profitable based on money paid by mobile operators in exchange for subscriber traffic.
