It’s safe to say that Shopify is pushing the absolute frontier of what’s possible with Rails and Ruby. Their main majestic monolith is a staggering 2.8m lines of Ruby responsible for processing over $100m in sales per hour at peak 🤯. And they’re doing it running latest Rails 🥂
I love – LOVE! – Ruby. I've written well over a hundred thousand lines of code in it over the past 18 years. Don't for a minute feel ashamed for loving your favorite programming language.
