As stated, I made the whole project from start to finish. I worked based on a schema (XSD), which had tons of possible mandatory, optional and non corresponding field combinations depending on variable data that's for the user to chose.

I developed and implemented the database schema, did the backend logic, ensuring a self-testing and dynamic XML generation code base.

The app also has a dynamic UI, which generates and validates fields upon the XSD.

Finally, I made the installing scripts and a built-in module that automatically checks for updates against our servers.

The idea was quite simple: we made a website for dispatch tracking of foreign trade operations, which could be reached from an Android app, built with Xamarin.Android.

This application would present a simple login screen, do the POST request of the credentials and load the website on a webview. The funniest part was the push notifications (we used Google's FCM), to which the user can subscribe through the website.

The whole idea was actually quite similar to a PWA, and we ended up delivering a version using that framework as well, although it was a requirement for the application to be in the Play Store (play.google.com/store/apps/details?id=despachosseguimiento.despachosseguimiento).
