I'm a data engineer for most of my day right now, and a lot of it is done with ruby/python/shell scripts into postgres DBs.

What learning path should I go down? I'm a solo actor at work with a lot of agency to decide my workflows.

I see myself building small to medium size data collections over the next year or two at my job.

Can someone point me to some learning?

I have a CS degree etc. and my title in software engineer etc. etc.

End users of my data usually like their data as a CSV that is then read using R or Python. However there is also a use case where I will build an app to view my data in a simple way.

All of this is completely doable with my current knowledge/workflow but I can't help feel like I do a data engineering job with very different tools than i see "data engineers" speaking about online.
