Nederadio
Because the industry is moving slowly in the direction of Jetpack Compose I've decided to rewrite the
Previously mentioned Sleeply source code into this new playground app called Nederadio.
In the app you can stream dutch radio stations. It is fully built in Jetpack compose, even dependency management is
added as a composable using Cokoin. It supports background playback leveraging Jetpack Media 3 and even casting is supported.
Koin is used for dependency injection and Ktor for HTTP network communcation. And ofcourse everything is written in Kotlin!
Take a look at the project page on Github.
GGD Contact
During the COVID-19 pandemic I have worked with the Ministry of Health, Welfare and Sport
on the GGD Contact application for Android.
The application is used for source and contact investigation for people with confirmed COVID-19 infections.
Used techniques are Jetpack navigation, MVVM, Kotin + coroutines.
You can find GGD Contact on Google Play
NS App
I have worked for over 2,5 years for the Dutch Railways developing the Android version of the NS App.
During this time I have completed numerous refactors and added a lot of new features. For example: I've introduced
MVVM and Kotlin in the codebase and doing so vastly improved the test coverage.
Other techniques used are: Dagger-Android and Mockk.
You can find the NS App on Google Play
IKNL PalliArts
While working at M2Mobi Amsterdam, I have partly refactored the app for IKNL which doctors in palliative care
use to support patients and family. The app contained a lot of guidelines and rules for palliative care. I have also added
features for doctors to calculate proper dosages for medications. Due to the nature of these critical features they
were developed using TDD. Other techniques that were used are RxJava2 and MVP.

AH Rappie
While working at M2Mobi Amsterdam, I have developed the pilot for a new delivery service for Ahold Delhaize called Rappie.
from the app users were able to order groceries from Albert Heijn and receive their order within 2 hours. Unfortunately the
pilot was not successful enough and the project was discontinued in 2018. Used techniques are RxJava2, Dagger Android, MVP,
Clean Architecture and ObjectBox.
ANWB Onderweg
While working at M2Mobi Amsterdam, I have co-developed the full refactor of the ANWB Onderweg application.

it is possible to view traffic information, find the cheapest fuel stations and start parking transactions from within
the app.
