Welcome to the school project section of my portfolio! In this section, I am excited to showcase a selection of the major projects I had to make at school. These projects represent my passion for learning, creativity, and problem-solving skills. Some I do not have access to anymore/ cannot release publicly. I have linked the available projects into their title(s)

• UMC Utrecht System consultancy Commissioned by the UMC hospital. We as a multidisciplinary team had to innovate and create a strategy for the hospital to overhaul their system in the upcoming year since their licensing was running out and support for the software was also stopping.
• Invoice System (distributed system) Working in a team of 3–4. Where we had short time to work together to make individual systems Using Java to make an invoice "department's" section of a domain driven distributed system. Something about the project is that it needed to evolve and become more complex with each iteration. As time went on it went from a domain project with postgres, to a cloud deployed system with asynchronous communication and noSQL Database Java, Docker, RabbitMQ, Swagger, Postgres, H2, Mongo
• Blackjack a restful api blackjack game separated in the domain, service & presentation layers Java, Spring
• Lingo a test driven development restful api wordle-like game (With Continuous Integration and 95% coverage) Java, Spring

Welcome to the game projects section of my portfolio!
In this section, I am showcasing a selection of projects I've worked on with unity. These projects are available to play, if so desired. These are games I had a ton of fun designing & developing. Models/Visuals used were free on the unity asset store or given to use/re-use.


Stars is a 3D snake game with educational elements.
In stars, you start out as a small snake with three hearts. You need to try to survive as long as possible as you grow and not hit walls or yourself, while gathering coins, points & power-ups. Once you get a purple coin you are prompted with a question, answer it right you get a power-up, answer it wrong you lose a heart.

This was my first unity project. Made with free assets from the unity store. The goal for stars was to see what it would look like if I could grab an old arcade game and add educational elements to it, while adding my own spin to it.
Stars was developed solo within a month.
GitHub, Build

Atomic Center is a local multiplayer 3D educational board game.
In Atomic center, you play as an astro-scientists trying to piece together the planet's forgotten periodic table. In this game you go around a game board trying to guess elements on periodic table.
Atomic Center can be played by 2–5 players, turn order is decided at the start of the game by rolling dice to see who rolls higher. Turn order is decided by highest to lowest. The game can be played alone, but some dynamic mechanics would not be as harsh. The player uses two D6 dices to move around the board. As the player moves and lands on different tiles, it has different prompts. You are not allowed to walk backwards; each time you pass the start you get a point.

Atomic Center is digitization of a board game I made. Made with free assets from the unity store. The goal for Atomic Center was to see what it would look like if I prioritized the educational elements first and then add gameplay.
Atomic Center was developed solo within 2 weeks.
GitHub, Build

Villa elektra is a 2D educational game.
In Villa elektra you play as a soon to graduate intern. You were commissioned to do you're next job at this villa but everything is a mess. In this game you play educational mini-games.
The mini-games range from quizzes to math questions
Villa elektra was made by Edwin van Emst, The goal for Villa elektra was to teach & test havo students with elektro techniek knowledge.
We were tasked as a group of students to add a few more levels and port the game to be a browser game.
My tasks on villa elektra:
• Made level 7.
• Made level 9.
• Made meterkast (in-between level).
• Touch functionality for most of the over-world.
• An analog touch joystick.
• Added a menu option to play the levels individually, allowing players to play the game on touchscreen devices.
• Fixed bugs and bugs in the game that prevented the game from being converted into a web game (WEBGL), then made the entire game available as a web game.

Other minor additions were:
• Increased the level max to ten.
• Added entries to access my levels in the over-world.
• The pause screen shows newer levels and level scores.
• Made accounts on GitHub & itch.io, for the next people who were to work on it.
Villa elektra was worked on for 2 months.
Play it now on Itch.IO

I also really like Hollow knight.
Thank you for taking a look at my portfolio.
Currently looking into making a 2d action platformer but want multiplayer into the game, so I'm using the recently released Unity's Netcode for GameObjects.
