GitHub Sponsors Profile
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:
App-vNext/Polly
domaindrivendev/Swashbuckle.AspNetCore
dotnet/aspnetcore
martincostello/sqllocaldb
martincostello/xunit-logging
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.
