I am willing to relocate for work — even abroad.

Other experience

Open Source Software

I ❤️ OSS. The collaboration it enables is truly wonderful. That’s why I like to contribute to projects I use and love, making them even better.

Some projects I have been involved in:


GitHawk is an iOS app that makes managing GitHub accounts and projects easier. I’ve been contributing to this app in a couple of ways, such as improving its accessibility, writing blog posts and developing new features. As of February 2019, I’m helping lead the project.

Check out the app on GitHub.


Moya is a network abstraction layer written in Swift. I’ve been contributing to this project by making their documentation even more awesome, working on the library’s migration from Swift 2 to 3, as well as helping 9ut users with any issues they might have.

try! Swift

try! Swift is a Swift conference held in multiple cities around the world.

I have helped out enhancing the iOS app for the conference to be more flexible and more easy to use.

September 2013 – July 2017

At Fontys, I studied ICT & Software, with a focus on Mobile. Here, I have been working with C#, Java, relational databases, Swift, Java for Android and more.


Delta is a Fontys initiative providing what could be called an excellence program for students:

“Students who participate in the Delta program work on their own goals and interests. They work on ‘exploration projects’, where they are given full freedom to explore a new technology or technique such as Google Glass, Drones, Virtual Reality and 3D printing. But this can also be collaborating on projects for real clients.”

Here, I made Opus, a Smart Mirror, making use of technologies such as Leap Motion, Kinect and more. This project went through a full cycle, from concepting to realization.


Swift, Objective-C, Git (& GitHub), Java, Ruby, Groovy, C#, SQL / PLSQL, PHP, Python, Continuous Integration, Scrum, Quality Assurance, Testing & Testability, Technical Writing.
