Thank you, everything helps. I agree completely with you, the actual CV I send out is linked at the end of the post, and I'll upload a tech-specific one now based on suggestions here.

For the past year I've been constantly on the brink of being on the street or worse and have been fighting tooth and nail to get even a sofa or any help at all. The vast majority of my family are back in South America and have problems of their own to deal with, my friends are not doing that much better. It sucks. No-one I'm applying for a job with would hear about any of it though of course.
