Bona Fides: I learned c on with the K&R book on an Amiga (and transitioned to enterprise software engineering from there).

This seems like one more "When all you have is a hammer, everything looks like a nail" take. I agree with the other commenters who advocate for best-of-breed (e.g. Kafka, etc. for a message queue). PS I freakin love PostgreSQL as a relational (or even a time-series or OLAP) DB.
