Hi 👋

I'm James.

I'm the author of ASP.NET Core 2 High Performance (second edition), a book about creating high performance web apps with C# and .NET Core (an open source and cross-platform framework from Microsoft - they are dropping the "Core" branding from .NET 5 onwards but it is the same open product). The book is also a large collection of tips applicable to making web apps perform well in any language or framework, full-stack from hardware to frontend.

I mainly work with C#, .NET and JavaScript/TypeScript/React but also work regularly with Python (v3 but also v2). I use Linux, Markdown, git, CI / testing automation and time-series databases (such as InfluxDB) almost daily too.

I maintain Huxley2, a cross-platform CORS enabled JSON ReST proxy for the GB railway Live Departure Boards SOAP API:

  • .NET Core ReST JSON web API
  • SOAP XML API integration
  • Azure DevOps CI/CD (YAML) and Azure hosting

I blog at about tech, the environment and many other things.

If you find my work valuable then please consider sponsoring me. I'm also available for hire.
