Isn't that just an API?
"build an application that reads an S3 bucket looking for uploaded sound clips, sends those sound clips off to a BDCA tool for natural language recognition"
Yeah, and how is the reading and sending performed? If you're doing all of that with only a few lines of code, you're basically just calling methods/functions in other libraries of code that you yourself haven't written. That's essentially how most API's work.
And as for " using little more than code snippets from Stack Exchange" I think you'll find that's how well over 50% of "developers" do their job.
I was going to use the joke icon, but I'm not actually joking!
