TeamCity to Azure CI/CD Migration Expert and YAML scripts creation from existing classic editor pipelines

I'm looking for an expert in .NET who can migrate my build agent from TeamCity to Azure CI/CD. This involves setting up the build agents, writing YAML scripts from my existing classic editor pipelines, and integrating the Azure pipelines with my current systems. I don't require any documentation for this project. Your ability to understand and write complex YAML scripts, coupled with your expertise in .NET, is crucial for the successful completion of this task.
