Bootcamp for security architect/engineer

I have doing security engineering and architecture for nearly 20 years now and AWS/Azure security for 7 years. But I feel lack of full stack coding experience and how web application, client and datastore works together using the magic of coding with authentication, encryption and authorization, makes me wonder I am still work in progress inspite having 20 years of experience. So wondering if coding bootcamp makes sense to me? I am not good at usingvfree online video learning or reading books except if its related to industry certification. Which bootcamp would you recommend even the best online ones? Thanks for making me a better learner !!
