I have a similar story I recently set out to build a SaaS product and wanted to use/learn elixir. I enjoyed using elixir but a lot of the fairly complex things I wanted to do requires quite a bit of learning and custom solutions. I wound up scraping that version after 2 months and rewriting it in Ruby/Rails in about a week. And adding new features.
I did the exact opposite: I have ~8years of professional ruby/rails experience and I was building a little SaaS. At some point, after 100 hours, I got bored/stuck with only 20% of the planned features to reach a MVP. I decided to switch to elixir/phoenix, where I had few confidence and there was apparently a growing ecosystem not always ready or complete. After 100 hours I completed the MVP and launched it. Using elixir was refreshing and right now I'm using it for almost all my side projects/prototypes.
