over three decades of software development experience covering a wide range of environments, systems, methods and philosophies that passed by or stayed over the years.

and still: i am hungry for more.

I have developed software for a huge range of devices, including iPhone, iPad, Apple Watch, Apple TV, Windows, and Linux, using languages like Swift, Objective-C, PHP, OpenEdge ABL, Perl, Python and many many more.

Since 2012 my passion is development for  Apple platforms. Mainly iOS / iPadOS but also macOS, watchOS and tvOS focusing on Swift / SwiftUI but coming from an Objective-C background.
