I am a game programmer and designer and I like to create simulation games!
I have always had a passion for games like SimCity, Kerbal Space Program and Cities: Skylines. Many projects I have worked on resemble that in some way. :)

About me

yellowArrow.gif not found

I am a game developer and designer that grew up in Groningen in The Netherlands. During my time growing up here and spending a lot of time playing games, I quickly became interested in gamedevelopment. When I was 11 years old I began creating really simple websites and one year later I created my own Minecraft server and wrote my own plugins in java. After finishing high school I went to study Gamedevelopment at Alfa-college and after that I went on to study at HKU (Hogeschool van de Kunsten Utrecht) where I learned most of what I know now. In my free time I like to play games with friends, cycle and when it's clear outside look at the stars.


Town building simulator

This project was made for my finals exam at Alfa-college, I made this project to learn more about Finite State Machines & town building mechanics and balancing. While developing this project I learnt a lot about letting people playtest my game, balancing and AI. This game was made in Unity and got me my diploma for MBO game development.


This project was made as my test final Exam for my studies at Alfa-college, I challenged myself to make a space physics simulator where space enthousiasts who may play "Universe Sandbox2" and "Kerbal Space Program" let planets fall into eachother and launch spacecraft from said planets. By combining some of both games' features it makes for a fun and informative experience. Making this game was a huge challenge because of all the maths I was unfamiliar with, this game was made in Unity.

PETscape from Home

This project was made when I participated for the Global Game Jam 2019 in Groningen, the theme was "What home means to you", some of my good friends and I decided to make a game where the goal is to find your pet that ran away from home. After finishing the event we even won a local award for visuals! During this project I did part of the design code, design & the particle systems.

This game was made in commision of Alfa-college and the Dutch Comics Museum, and was made to be played by young visitors of the museum between ages 8 and 14. To make this game appealing for the children to play, you play as a small child who gets trapped inside a comic book; and needs to find its way out. The 2D sidescroller-like gameplay makes it intuitive and easy for children to play. This game was made using Unity.
