Experience

  • Video Web Service

    This web-based service is written in Django. Two third-party companies provided content through APIs for our video team. The content available in the APIs and stored in the database included metadata like movies' names, descriptions, images, trailers, etc.

    The service had a couple of APIs to show the content and interact with users, such as contentDetails API that shows the metadata of movies or series. Others include a voting API, a comment API, and a Play Info API which provides an HLS link for playing the content and available subtitles. Additionally, this web service includes metrics for tracking user interactions with the service, like total watching time and total bandwidth for different application versions. Data scientists work with these metrics to offer better suggestions and user experience.

    The service used Prometheus for monitoring and alerting. There were three types of metrics: basic-level metrics like CPU and RAM usage, mid-level metrics like the response time and call count of APIs, and high-level metrics like the users' watch time. Using these metrics enabled them to monitor the service and get notified whenever something was wrong.

  • Video Ads

    This web service is written in Go to allow advertising in video content. Video web service calls this service whenever it wants to respond to a request for playing video content. Based on business logic, bidding, and video tags, it selects a video ad in VAST or VMAP format and sends it to the video web service. It had a panel for companies to create their accounts and set their prices for an advertisement. After the company qualifies, its ads are inserted into the database and played during the video content whenever it is a good match.
