How does someone who wants to do this for a career transition from hobbyist to employed?

I've been working on this since the Kindle books came out, and before then I struggled with "Realistic Ray Tracing (Second Edition)". The trilogy let me understand that book and despite the occasional flub with the order of operations, I've got OBJ loading in, a few BRDFs, etc. When the pandemic hit, I started working on this more heavily to stay sane. I know now that this is what I want to do with the rest of my life. At what point do I start showing what I am making, and where do I show it? Where does my skillset need to be to get started in the industry? Thanks!
