Cloud: Azure (App Service, Functions, Container Apps), AWS (Lambda with the .NET runtime, ECS), Google Cloud Run, and Kubernetes. Infrastructure as code in F#: Farmer (Azure ARM DSL) and Pulumi (supports F#).

CI: GitHub Actions actions/setup-dotnet, dotnet restore/build/test, Fantomas check (dotnet fantomas --check .), and code coverage.
