Thanks to linux academy. I like to share quick feedback on developer course, it is very comprehensive and not just targeted at achieving certification. Good compared to others in the market.That being said , I wish the developer course is more interactive like AWS architect( the one TOM teaches, I enjoyed that course very much)course because the instructor here seems to be going too fast at times with no text or diagrams on the screen on few topics like Mobile push notifications etc. I had to read the product documentation to understand. Some times I felt overwhelmed to take it with out any concept diagram or text on the screen, it gets too theoritical with no concept diagram. I hope you improve that part. Some videos are outdated.
