    Where We Went

    • 3D Game
    • Unity
    • Game Design

    Where We Went is a narrative-driven puzzle game where the mysterious main character can control ancient guardians to solve puzzles. As a game designer, I focused on level and puzzle design, gameplay mechanics, and player experience. I also playtested the game, deliberately testing mechanics and edge cases to identify and reproduce bugs. We used those findings to improve the player experience and game stability.

    Tuinder is a mobile app that helps users make their gardens more sustainable and biodiversity-friendly with AI-powered recommendations. Through a swipe-based system, the app builds a personal profile to generate a garden tailored to the user’s preferences and limitations. During this interdisciplinary project, I was responsible for the front-end development of the app. I collaborated with a designer to improve the UX/UI, as well as with back-end developers to integrate the front-end with the back-end services and AI functionalities.

    Twisted trail is an endless runner where the main character, Marc Whelan, runs through the forest trying to gather evidence of the strange creatures that live on the trail. I worked on this mobile game during my minor, collaborating with another developer, a game designer, and two artists. My main tasks were related to the functionality of the creatures, such as their abilities and behaviors when the player interacts with them.

    Internship Report Website

    • Grade 10/10

    For my internship report, I created a website to showcase my experiences and projects during my internship at DPDK. I dive deep into the projects I worked on, the technologies I used, and the skills I developed. The project received a grade of 10/10.

More about me

I recently graduated from Creative Media and Game Technologies (CMGT) at Rotterdam University of Applied Sciences.

I’m most interested in what a digital experience means to the person using it. What are they trying to do? What do they need to understand or feel? As AI takes on more and more routine coding tasks, my focus has shifted toward the parts I enjoy most: understanding users, shaping the experience, exploring ideas, and refining the details.

That curiosity also shows up in game design. During my Minor I loved creating levels and puzzles, imagining the different ways someone might solve them, and then trying to break them myself. It's a fun way to find out what works and what doesn't.

I’m easy to work with and open to other perspectives, but I’ll speak up when I think something could be better. Outside of work, I enjoy gaming, baking, and spending time with my partner and our dachshund.

    FinOps Gamification / Graduation Project at a.s.r.

    During my graduation internship at a.s.r., I independently researched, designed, and developed a gamified web prototype to encourage cost-conscious cloud behaviour. I translated research on FinOps and behaviour change into requirements and user stories, then used functional and usability testing to improve the solution.

    Game Design & Development Minor

    I worked on 2D and 3D games in Unity. On the main 16-week project, Where We Went, I focused on game and level design while actively playtesting, finding and reproducing bugs, testing edge cases, and improving the player experience. We worked as an Agile/Scrum team and used ClickUp to manage the project.

    Interdisciplinary Project

    During the second half of my third year at the Rotterdam University of Applied Sciences, I participated in an interdisciplinary project where I collaborated with students from various disciplines to create a mobile application. This project allowed me to apply my research-, design- and front end skills in a real-world setting while working with a diverse team.

    Year 2 Creative Media and Game Technologies

    In my second year, I worked on a range of technical projects. I built an MVC web app using Laravel, a full-stack React application with a RESTful API and CRUD functionality, and a mobile app with React Native and Expo GO. I also developed a platform game using pose detection, powered by a self-trained neural network.

    Year 1 Creative Media and Game Technologies

    In my first year, I built a foundation in both front-end and back-end development. I created a basic HTML/CSS/JS website, developed a PHP reservation system with MySQL, explored CSS framework Bulma for styling an informational site, and made a simple runner game using the Excalibur Game Engine with basic object-oriented programming.
