Recommendations needed: Education as a technical software writer

Hey, all – I'm a technical writer for B2B SaaS companies and looking to improve/elevate my skills. I'm solid on middle and top of funnel content, but I'm looking for some recommendations on the devops side for when my audience is made up of mostly engineers. Obviously, the main skill is being able to "speak two languages" between C-suite/non technical folks and developers. With all that beings said–what are some of the books, courses, and resources that you've built your knowledge and understanding on? (I know that's super broad, casting a wide net here). Additionally, what languages/practical knowledge do you find yourself wishing writers in software development space had when content is hollow/inaccurate? Thanks!
