Rosoftlab s.r.l.July 2018 - Présent

Responsible for the development and maintenance of several android applications for different industries.

1) "OPIRIA" is an application developed from scratch having in mind the Clean Arhitecture and SOLID principles. Implementation it based on:
- Kotlin, RxKotlin, Koin;
- Retrofit, GSON, Room;
- Firebase (notifications, dynamic links, crashlytics);
- WorkManager (used to run things in background, like uploading);
- TensorFlow (used to detect user emotions while using the app);
- JsonLogic (used to send logic from server to the client);
- ExoPlayer, Glide;
- Video compression;
- Zebra Crossing;
- OpenSreetMap.

This project was implemented in close contact with the customer using a Scrum working approach and for source code management we used GitLab.

2) The second application implemented from scratch and released was for one of the biggest chocolate factory in Switzerland, Chocolat Frey.
The app is written in Java and C++ (Android NDK) using Android Studio and is able to create augmented reality experience using device camera and different markers.
Depending on the video frames the app can show:
- Different augumented reality 3D models;
- Different surveys which user can respond on;
- Audio (UDP connection was used) ;
- Video (using Android Media Player)
- Custom views and animations, jumping and moving different objects on the screen, playing Gifs, etc.

The first difficult point was to develop a native C++ module for detecting and getting the position of the marker in images. For this it was used: Android NDK; CMake; OpenCV; Aruco markers
The second point was to draw an augumented reality 3D model on a device which doesn't support ARCore. For this it was used LibGDX library modified for our needs.
The last point was to make a content management system for the client and for its implemtation it was used:
-RESTful APIs; RxJava; Retrofit; OkHttp; Moshi JSON parser; CRUD operations on internal files.
