Ruby on Rails
Ruby on Rails, often called Rails, is a popular toolkit for building websites and web applications. It uses the Ruby programming language and is known for helping developers create websites quickly and efficiently. Think of it as a complete set of pre-made tools and rules that developers use to build everything from small business websites to large platforms like Airbnb or Shopify. Rails is particularly loved because it follows the "convention over configuration" principle, which means it has smart defaults that save developers time. Similar systems include Django (for Python) or Laravel (for PHP). When you see "Rails" mentioned in a resume, it's referring to this framework.
