About Ruby on Rails
Ruby on Rails is the web framework that popularized convention over configuration — Shopify (4 million merchants), GitHub, and Basecamp are all built on Rails.
Convention over configuration: `rails generate scaffold Post title:string body:text` creates controller, model, migration, and views in one command. Convention defines where everything goes — no decisions required.
Active Record: expressive Ruby ORM. `User.find_by(email:email).orders.where(status::paid).sum(:amount)` reads like English.
Hotwire: Rails'' answer to React — Turbo Drive, Turbo Frames, and Turbo Streams enable interactive UIs without a JavaScript framework.
Shopify runs on Rails at 4 million merchants — proving Rails scales with proper infrastructure.
