I switched from physics to full stack dev. Granted, some consider that a small leap but I promise I was terrible when I started.

This is basically "just a confidence thing" with a dash of accepting a pay cut.

My advice:

Code on the weekends, see it's fun.

If it's fun take a bootcamp, or better yet, build your own project.

When they ask for your experience, can your self a junior.

And when they ask for your preferred wage, ask for a low number.

Get paid to learn. The market in Canada is desperate for talent.
