Senior freelance software engineer with professional development experience since 1997 and
independent consulting experience since 2003. Open for remote engagements, hybrid in Copenhagen or Aarhus or on location in Aalborg.
Specialist in maintaining, refactoring and extending native macOS and desktop applications, with a background in cross-platform C/C++, mobile applications and development of firmware and electronics for embedded systems. Recent projects include Objective-C, C++ and Swift maintenance for Lumivero and a ten-year engagement with ATLAS.ti spanning development for macOS, .NET, Python/NLP and iOS. Available for both, short assignments and longterm projects. My working method combines independent research and rapid
prototyping with careful, maintainable implementation, allowing me to adapt quickly to each client’s
technologies, architecture and working environment.
