I suspect that this sort of design wouldn't come up a lot, but do you think about the difference between this experience and the experience of designing something where you used a workflow that you were familiar with? Or put another way, if you did this again, would it go faster or would it take the same amount of time?
But aside from that, I would still say yes. I've learned a lot (it's just hard to put into words when I'm missing some of the technical language) and I've gained so much confidence in even dealing with code.
I've actually started doing some work for someone after they saw my site on Reddit, which I could never have done before. It involves Docker, a bit of Python, and working on a codebase with multiple contributors. It's both exciting and terrifying at the same time.
