I am 55 and full-time @home on oxygen therefore I cannot do the job I did before this happened, so I needed something to do to earn some income and decided a year ago I can program from home and started to use Mitch and others to teach me on YouTube and Subcription's like this, It is super helpfull, Thank you very much Mich. After the "Powerful Android Apps with Jetpack Architecture" Course I will have the last bits I need to complete my 1st App then I'll make 2 for the AppStore! I also wrote the backstack API in Kotlin (SpringBoot) first it runs on a Linode server on Tomcat (WAR)
