Paul Johnson is a Senior Developer with 23 years of experience building cross-platform software, from kernel-level drivers for RISC OS to modern mobile apps using Xamarin and .NET MAUI. He specializes in C# and C, with deep familiarity in C++, FORTRAN, VB.NET and legacy systems, and a pragmatic focus on portable, low-fuss code across Windows, Linux and macOS. Paul has a strong mobile track record—contributing to Xamarin.iOS samples and modernising iOS sample apps to AVFoundation—and has led mobile teams and projects for numerous companies. As a qualified physical chemist and former lecturer, he combines rigorous analytical thinking and teaching experience with hands-on engineering and server administration. He is an active open source collaborator (Scribus, OpenOffice, Mono) and a long-time editor in the developer community, reflecting both technical depth and commitment to knowledge sharing. Based in Merseyside/Manchester, he prefers remote-capable roles and is selective about language stacks (does not develop native mobile apps in Java or Objective-C).
