I actually end up doing a lot of both working in a company with a huge infrastructure but small number of developers. I would recommend to start solving some of your own problems in the devops space with some REST APIs and frontends :), maybe a self service web UI for developers to create VMs with some of the stack already there and configurable? (Think Heroku) I have worked in the past 5 years sometimes as 100% React frontend for a medium size project, sometimes as 100% backend developer architecturing effective data structures and data access patterns and sometimes as 100% devops setting the Ci/Cd/Ansible/Docker workflows... Worth noting that in the beginning of my career I worked with digital signal processing in FPGAs and embedded Linux. I dunno, I feel it is all the same thing. "Specializing" do you mean learning a particular framework? Frameworks change all the time... otherwise, they all run in computers with OSes, CPU, Memory, Disk and I/O. I would recommend learning the underlying technology and then you can quickly learn anything (literally).
