You probably don't need a bootcamp.
You're experienced enough to get good by doing courses online.
Just get over the fear of picking technology that will be outdated and do a course right now. Vuejs or React for the frontend and Laravel for the backend.
If both backend and frontend end up being too much, maybe focus on the one you like better.
Learn to deploy to AWS. Learn how to make a CI/CD in Github Actions to deploy for free.
Boom, you've done a bootcamp (or a bunch of them actually).
Now all you need is 10 year experience to get hired by companies... oh wait you already have it ;)
