Kind of mottled experience, but for more than 10 years I was a technical editor and rewriter for a large research lab before getting shuttled into HR work. Total teaching experience spanned about another decade, though it's hard to assess the timing because much of it was part time, but my post-retirement swan song course was at a top university. Mostly lived as a programmer for about a decade. Two of my working visas officially described me as "engineer" and "professor", but I don't remember asking for such tags. My old visa description was something like "4-1-15-3" but I lost my visa category long ago. Now I just read stuff in a state of days that feel long while the years feel short...
