I always do intro/cover letters tho, and have something like “Professional Contributions,” and Education listing F/LOSS with my mid-career CS degree, like extra-curriculars from coding.
Hm, yeah. I don't really have much of a formal education to rely on, I was unschooled. It's an awkward thing. Personally I don't feel that my work is particularly good, especially since I don't have a specific yardstick to work off, but the people I've worked alongside or have shown it to have told be that I'm 'very knowledgable', which feels weird.
I've been wondering about spending on some AWS certifications and the like just to improve the 'qualifications' section, or hiring someone to look at my CV and give a professional opinion on it.
