Did you ever think about becoming an entrepreneur? You have an interesting set of skills that would give you at least some start, of course, you would have to learn some things about marketing and branding. Check indiehackers.com maybe you get some ideas. I have the same problem as you, it seems product managers and CEOS have multiple skills.
I remember cleaning a couple of client's wordpress sites that were infected with this hack some years ago, during 2015 if I remember correctly, it was hard work. It seems many sites were infected with this kind of spam at the time.
