London, UK

I like to develop software with C# for .NET (and sometimes TypeScript...), and do so in the open for all developers to benefit from where I can.

As well as publishing open source projects as NuGet packages, I also maintain a number of projects that serve as examples of approaches to different problems I've encountered and solved along the way.

Projects I regularly contribute to and/or help maintain include:

I also enjoy contributing issues, fixes and new features to others' projects to give back to the community and improve the ecosystem as a whole when I encounter issues and have suggestions for new features and/or improvements.

@martincostello

Having a small number of community sponsors would help keep me contributing to open source projects for the .NET community.
