OP has actually fallen behind skills wise.

This is why companies have been moving Cloud First - your DevOps/SRE or even your Dev team can also be your Networking and Security team.

The writing was on the wall for Network Engineers and old school Sysadmins almost a decade ago, and why so many transitioned into becoming Infra, DevOps, SRE, or Security SWEs or joining Security and Cloud companies as Sales or Support Engineers.

Edit: OP seems technical enough (assuming they know how the difference between Podman vs CRI-O, how to code a DFS from scratch, and what Netlink is), but isn't selling their skills right. They need to invest better and think about how to better tailor a resume.

Not having a LinkedIn is also career suicide at this point.
