Web Application Developer

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.

I have worked on quite a few Android apps now using both Java and Xamarin. Most apps I've worked on were small business apps, but I have also worked on one larger project.

Json was used in one form or another for pretty much every app I've worked on in the last 5 years.
