I believe I can help you with:
You present your work or idea and I will try to help with advice, a review or a solution to a potential problem.
But, rather than writing an email or scheduling a call, I require you to record a screencast instead.
In my experience, emails or issues on GitHub that I've received so far, usually lack sufficient information about the problem and I think a video is a good alternative.
However, a video call is another form of "sync communication" which is why I think a recording is more suitable (especially in the beginning).
You can always send a message for free and I will answer when I'm available.
If you see a value in my services and want a longer term relationship, I'm open for your offers. My price depends on hours per week/month you require and the type of project and work conditions (remote, flexible or something else).
