Ruby on Rails: Build robust web applications efficiently
Ruby on Rails, often shortened to Rails, is a popular open-source web application framework written in Ruby. It provides a structured approach to web development, allowing developers to build complex applications quickly and efficiently. Rails emphasises convention over configuration, meaning developers spend less time setting up and more time building. This makes it an excellent choice for startups and businesses looking to get their products to market rapidly.
What to look for in a Ruby on Rails freelancer
When hiring a Rails freelancer, look for a strong understanding of the following:
- Model-View-Controller (MVC) architecture: This is the core architectural pattern Rails uses. A solid grasp of MVC is crucial.
- Ruby language proficiency: Rails is built on Ruby, so strong Ruby skills are essential.
- Database management: Experience with databases like PostgreSQL, MySQL, or SQLite is vital.
- Testing and debugging: Look for experience with testing frameworks like RSpec and debugging tools.
- Version control (Git): Essential for collaborative development and managing code changes.
Main expertise areas to inquire about
Rails developers often specialise in specific areas. Consider your project needs and inquire about their expertise in:
- API development and integration: Building and integrating with RESTful APIs.
- Front-end development (HTML, CSS, JavaScript): While Rails focuses on the back-end, front-end skills are often necessary for a complete product.
- E-commerce development: Experience with platforms like Spree or Shopify integration.
- Database optimisation: For performance-critical applications.
- DevOps and deployment: Experience deploying and managing Rails applications on platforms like Heroku or AWS.
