Custom Goods Imports/Internal
January 2021 - September 2021

Description: SwissPost for Imports is an internal application for imports and exports through the country’s customs. This application helps streamline the process of receiving and sending out packages over the border of the country. This is aiming to replace the legacy system which proves to be slow and not future-proof. This application is written with Angular 12. We use SignalR to have real-time communication with the backend, so the app always has the latest data to work with. We use Indexed DB to cache data and service workers to sync up data so the app can run offline in case of connectivity issues. This app works with a barcode scanner for most of its operation, so users don’t have to touch the keyboard or mouse while working. This helps speed up the process by as much as 25%

 

Role: I worked as a full-stack engineer with 60% of the time working on the front-end.

During my stay, I helped design the real-time communication from the back-end to the front end using SignalR.
