But I recommend not doing one. You are skilled enough that you could dedicate yourself to 3 to 6 months of serious study of the technologies you are interested in. Teach yourself by doing projects that interest you, and then use those projects as evidence of enthusiasm and experience.
Boot camps might be beneficial if you don’t feel capable of teaching yourself, but they will have so much training-wheels stuff that you are well past so it will be a mixed bag of value. Plus it costs a lot of money.
I don’t think the fact you did a bootcamp will increase your value much. Certainly not as much as self study and projects in a public git repo.
