I did a flask application that read an AWS account's glue resources, displayed them based on category (tag of "databasename" and "driver" etc) and offered the ability to run those jobs in serial or parallel, with a combined job status page for each batch. It also used company colours because I told it to pick a colour palette from the company website. It worked first time and produced sane, safe code.

There was a second shot, which was to add caching of job names because we have a few hundred now.

(Context: I'm at a company that has only ever done data via hitting a few hand replicated on prem databases at the moment and wanted to give twitchy folks an overview tool that was easy to use and look at)
