New system build and legacy app modernisation & updating done right
After working for more than 25 years in the Software industry, including many projects for public sector clients such as the NHS, National Strategy for Police Information Services and Ambulance & fire services, I have seen the good, the bad and the ugly of large and small scale projects.
I've worked with all major technologies and stacks over my career, including Microsoft .NET / .NET Core, Azure, Node / JS etc as well as mobile development with Xamarin / React, and my experience means I'm always able to hit the ground running and add value quickly
As well as undertaking new (Greenfield) development, I'm also happy taking Brownfield existing code and systems and updating them to newer technologies and architecture, while ensuring as much of the existing code is reused as possible to keep down costs and maintain confidence in the existing business rules, or adding new features to existing systems. I've also provided new mobile apps to existing legacy systems on both iOS and Android
