What's Up! Luxembourg
What's Up! is a community mobile app for the Grand Duchy of Luxembourg and its regions.

The app's main feature is to show events in the region on a map or in different interfaces. People can create and share events with everybody else or rate them. Other features include real-time public transport information and real-time statuses of public parking spots, and real-time fuel prices. The client-side is developed with Xamarin for iOS and Android, and the server-side is developed with ASP.NET Core, allowing a high ratio of code sharing between all sub-projects.

The Replicate tools help cross-platform mobile app developers supercharge their resource and asset management pipeline by automatically performing resource synchronization and image resizing tasks. Available as stand-alone apps or a Visual Studio extension.

RedCorners SDKs
Components to supercharge your .NET software development experience. RedCorners libraries offer essential extensions to Xamarin.Forms iOS and Android projects, localization frameworks, Google Maps wrappers for Xamarin.Forms, local object storage extensions, EXIF readers and writers, unified APIs for reading device contacts and performing place searches, as well as easily communicating with popular video streaming services such as Vimeo and YouTube.

Whereseek is a new way to discover, search, create, and share points of interest and events around a region.

Cocos2d-x Beginner's Guide (Second Edition)
One of the books I reviewed about Cocos2d-x game development. It is a great book for anybody who wants to start developing mobile games with C++ and Cocos.

Traces of Love (Mobile Game)

The goal of this project was to use the very abstract concept of lines and shapes and put a rich story on top of it. The game was released on Valentine's day in three languages (English, German, and Luxembourgish) and was featured on local Luxembourgish media websites. Made with Unity.

Magesture - Magnetic Interaction with Mobile Games

Created an algorithm which detects changes in the magnetic field around the mobile device. A passive magnet can be used as an input device. In this case, an ordinary whiteboard wiper is used as a joystick. Three games were implemented in different genres using Cocos2d-x and C++ to demonstrate the effectiveness of this novel input method in those genres.

Kinect Air Touch/Hand Tracking Library for XNA

This library allows developers to add two hands to their XNA-based games to perform air touch gestures. Uses Kinect SDK. This video demonstrates this in a game called Cows in Space.

KISS - KInect Security System
KISS is a home security system that utilizes Kinect to track skeletons and take snapshots while people are present in the room.


PICK'R is a mobile app available on the iOS and Android stores, which gives you points for good driving. You can use these points in the lotteries and win prizes. I developed the apps for Motion-S SARL.

Les As Du Volant

A project done at Motion-S SARL for Foyer Insurance Belgium. The mobile application records your driving traces and scores them in various categories such as acceleration, braking, steering, and cornering. Scores are compared against other drivers in periodic ranking tables, and users can win prizes. Released for iOS and Android, written in Objective-C and Java.
