Project description

Client is an American e-book and audiobook subscription service that includes one million titles. Platform hosts 60 million documents on its open publishing platform.
The platform allows:

  • anyone to share his/her ideas with the world;
  • access to audio books;
  • access to world’s composers who publish their music;
  • incorporates articles from private publishers and world magazines;
  • allows access to exclusive content.

Core Platform provides robust and foundational software, increasing operational excellence to scale apps and data. We are focused on building, testing, deploying apps and infrastructure which will help other teams rapidly scale, inter-operate, integrate with real-time data, and incorporate machine learning into their products. Working with our customers in the Data Science and Content Engineering, and our peers in Internal Tools and Infrastructure teams we bring systems-level visibility and focus to our projects.

Client’s goal is not total architectural or design perfection, but rather choosing the right trade-offs to strike a balance between speed, quality and cost.
