I have 8 years of development experience with PHP, React, React Native, and honestly it's time to respecialize. AI Agents made the market more competitive, i struggle to find a good salary, and anyways I'd like to accumulate enough for a strong CV to be hired by a US company and migrate there with a work visa. I started the most basic of his courses which have linear regression models, gradient descent, and needs knowledge on algebra and calculus for limits and derivatives. This is quite a steep learning curve for me as i needed really to get up to date with maths. I never went to college, always learned everything online. Is this the best way to enter? The most robust one, for those of us who have ambitions to become very serious and involved engineers that want to create big things? (Not somebody that just wants to land a comfy job, working cozily without too much effort)
