I've been an iOS developer for 8 years. I have experience with both Swift as well as Objective-C. Over time I've mainly focused on building business apps. I've worked on both small and big business apps, examples would be a tablet app for a large Dutch grocer, a whitelabel app for musicians and sports teams, an app for measuring reverb in a room, etc... As a hobby I like to work on games using Apple's SpriteKit technology.

I've worked several years as a .NET developer, creating mainly apps for small and medium sized businesses. Most of these apps would include an SQL database and some networking. I also have experience writing mobile apps for iOS and Android using Xamarin.

At Backbase I worked on a white label app for banks. The white label app would contain several components, for example a portfolio component, a payment component, a contacts component, etc... Banks could mix-and-match these components to create an app.

The core of the components was written in Objective-C and the demo apps were written in Swift. Each component was distributed as a Cocoapod. I worked on most of the components and an older version of the white label app.

At Backbase we worked in a multidisciplinary agile team having iOS & Android developers, testers, designers, a Scrum Master & Product Owner.

I am the owner of Wolftrail. Within the context of Wolftrail I do both freelance work as well as work on my own apps. During 2016 I had a sabbatical and in this time I've worked mainly on a Bomberman game using SpriteKit, but as of yet this game is not yet released.

My goal is still to, somewhere in the future, release this game for the AppleTV.

At Ahold I worked on a new tablet app as well as maintained the existing phone app. I've also setup Calabash for unit testing and created UI tests. The tests (like Calabash) were written in Ruby, so I did a bit of Ruby development here as well.

Within Ahold I worked as part of a multidisciplinary team having iOS & Android developers, testers, designers a product owner and a scrum master.
