  6. Superb teaching technique for AWS development. I like your way of teaching. first only API gateway (get request) then add how API gateway and lambda function works and then add DB table and finally how API, LAMBDA, DB and static website works each other.

  7. Very nice clear, breif and precise. Most of the AWS tutorials start after 30-40Mins which is really annoying, but yours is completely straight to the point. Thank you very much. Subscribed.
