Suite of Client-side Projects in Angular (7+) and Server-side Auth
Among the two main ones, one was used embedded on the physical device in Chrome Kiosk Mode and the other was the management app for the devices (which were connected via Azure IoT).
Some aspects of the project:
* Lead the client-side development team in best practices and architecture
* Performance critical system (the embedded device had a weak CPU)
* Configurable dashboard
* Create multiple UI components and use local NPM to manage package sharing
* The web app also hosted the device code in iFrame, taking multi-versioning and support into consideration
* Authentication/authorization implemented for both solutions for the client- and server-side managed by Azure Active Directory B2C
