Would appreciate any suggestions for getting hired or funded, I've got valuable skills but am struggling to find career opportunities
I'm not sure that the exact subfield of algebra is important outside academy. Try to give more relevance to your generic skills.
Most of your projects are written in Julia. Do you have one in C? (Some people like "canonical" languages, not me, but other people do).
Do one of your projects produce nice graphics? Nice graphics are good for submissions. (Some project are very interesting and important, but don't produce nice graphic. Anyway, that "photo" of a black hole is worth a thousand pages of grant request paperwork.)
Since I am working on scientific computing, I would use Fotran instead of C language, with which I have experience.
Geometric algebra isn't my only skill, but it is what sets me apart from most other programmers out there.
Geometric algebra can be used to make more efficient transformations in almost any field, including: automatic differentiation, optimizing electronic circuits, computatations involving relativity and spacetime, machine learning, and countless other scientifc computing applications. It is still largely unexplored in terms of applications and has very much to offer.
Reading again my comment, a part of it is very badly written. I wanted to say that if someone is hiring you, they will not care too much about your specific specialization. I didn't want to say that the field has no application.
If you want to continue working in someone related to your field, you probably have to make a few blog post with some interesting application and explanations about how the algebra helps, so someone with a similar programs perhaps may be interested in hiring you instead of learning algebra.
Put a few graphics, so the advantages of the algebraic approach is easy to see. Don't make it too long or too short. Don't make it too technical or too diluted. Hopefully I could give more detailed advice. I can't guarantee that you will get a job, but hopefully we will enjoy a few nice blog post here :).
As an example, I like the post of https://news.ycombinator.com/from?site=righto.com they are very technical, but not too much. They have always a few photos and diagrams. (But some fields are not easily photographable.)
