The startup DemoUp provides a service which allows to add video content automatically to whole Online-Shops, not requiring the customer to do any more than add a script tag. I created and maintained the whole front-end of DemoUp, which included development of:

  • an integration framework which builds specific script files for connecting the Online-Shops.
  • code that adds a play button for videos to a specific position in a product page, and extracts required data from them in 11kb of code including styles and images.
  • a video player with my custom solution, based on preact being less than 25kb in size including styles and images.
  • a dashboard based on React.js which is used internally and externally to build and control DemoUp's video database and provides insights into statistical data, using D3.js based charts.
  • the DemoUp homepage which is a very fast Single-Page-Applikation with full support for search engines.

Additional non-frontend work:

  • an automated system which bills customers based on their tariff.
  • a custom system for monitoring all services.

Here you can find more details about my work for DemoUp.
