All right, it makes more sense now
some disclaimer though, i am person that balancing devops engineering and backend duties and i would say most people will not be able doing that. people rarely have apptitude to do infrastructure engineering duties. It would be probably far easier career for you just to concentrate on becoming excellent backend dev+ front. but if u will learn eventually infrastructure skills and will find yourself at comfort solving infrastructure related stuff, working with linux, AWS and all cloud configurations, terraform, pulumi, ci cd and etc. With diving deep into configuring monitoring, tracing solutions, customizing them, intergrating with AWS,kubernetes whatever. Then feel free to join this path
