I've got a whole list of tools you might want to consider checking out over at [1]. The scripts themselves are Ubuntu specific, but the binaries are ones I've all found very helpful over the years.
In particular I'd call out `gron` (make JSON greppable) and `lnav` (Datadog-level log filtering but for local machines and files) as very helpful for dev work.
