Rails
Rails, short for Ruby on Rails, is a powerful and popular open-source web application framework written in Ruby. It provides a robust structure for building dynamic websites and web applications, allowing developers to focus on creating features rather than writing repetitive boilerplate code. Rails emphasises convention over configuration, meaning it offers sensible defaults and encourages best practices, leading to faster development and easier maintenance.
What to look for in Rails freelancers
When hiring a Rails freelancer, look for demonstrable experience with the framework, including a solid understanding of its core components like models, views, controllers, and active record. A strong portfolio showcasing previous Rails projects is essential. Check for experience with relevant testing frameworks like RSpec and Minitest, and version control systems like Git. Excellent communication skills are crucial for effective collaboration and understanding your project requirements.
Main expertise areas within Rails
Rails freelancers can specialise in various areas, including:
- API development and integration
- Front-end development with JavaScript frameworks like React, Vue, or Angular
- Database design and management (PostgreSQL, MySQL)
