I am in Operations. I use it (and pay for it) because the free version seemed to work best for me compared to Perplexity (which had been my go-to) and ChatGPT/OpenAI.
My job title is Senior DevOps Engineer. I have no high school diploma and what they call "some college" (less than 2 years). I've been working as a sysadmin since the late nineties. I've done stints as a Director of Operations, and entrepreneur (trainer/consultant). But mostly ops work. I've been working remotely for the past 3 years (thanks COVID!). I live in a rural area. I try to put in about 40 hours a week, it's been a bit under recently as we're moving and it's been a distraction. The job opening was posted for under 200K but I asked for a bit over and got it. I was told my experience and enthusiasm was far above the other candidates. Hope this helps! (I majored in biochemistry when I was at uni.) I'm in Texas now.
Sounds like a job for the AWS Athena service. Put all the files into S3 and you can query across the whole collection. See https://aws.amazon.com/athena/
