GRAYBOX designed and developed a custom Ruby on Rails web application for ArtbeatsExpress. The application allows Contributors to upload various formats of media; manage the keywords and merchandising info; and list that content for sale on the ArtbeatsExpress site. Content is automatically transcoded into a variety of formats and resolutions based on the original file format. Our subscription module manages recurring billing and monthly distribution of credits that subscribers use to purchase content. Contributor royalties for purchases are automatically calculated each month based on site activity. The site is integrated to Amazon's S3 for storage; EC2 for processing and transcoding content; and uses PCI compliant systems for credit card storage and charging. This combination provides flexibility for on-demand scaling of resources as needed.
