I've been playing around with Arduino and esp for ~10yrs, just googling, copying around code snippets, and reading compiler fail logs.

I'm fed up with my lack of ability to understand larger projects and more in depth programming (pointers, objects, etc)

I'm mostly focused on embedded software (iot, iiot, etc.) So probably looking at staying with C,C++ or rust?

I'm fine with investing some $$, but don't particularly feel I want to spend more that $1k at the moment to fix my ignorance.

What bootcamps would you suggest?
