You can book remote consulting sessions with David here.
Sessions require you have access to at least a microphone (and ideally webcam!) and the (free) Discord client (for chat and screen sharing). You'll receive an invite to a private Discord channel for the duration of the session.
If you would like to do remote pairing, or a more code focused session, please have Visual Studio Code (or VS Community) Live Share installed and setup.

Recommendations for hands on sessions:
By default I support: C#, TypeScript, JavaScript, Kotlin, Python, Java, C, C++. Other languages, please confirm by email / twitter up front.
The more prepared you are, the more effective we can be :)
