What's the difference between a Junior Ruby on Rails Developer and a Senior Ruby on Rails Developer?

Distinguishing between junior and senior Ruby on Rails developers can be challenging, especially when evaluating candidates. The key lies in understanding their experience levels and the depth of their technical skills.

Junior Ruby on Rails developers typically have 0-2 years of experience. They possess basic knowledge of Ruby, Rails, HTML, CSS, and JavaScript. Their responsibilities often include working on individual tasks and bug fixes. They write basic unit tests and are usually mentored by more experienced team members.

Senior Ruby on Rails developers, on the other hand, boast 5+ years of experience. They have advanced skills in Ruby, Rails, JavaScript frameworks, and DevOps. These developers take on architecture design and team leadership roles. They establish coding best practices, implement comprehensive testing strategies, and mentor junior developers.

The gap in problem-solving abilities is significant. While juniors tackle defined problems, seniors address complex, undefined issues. Database skills also differ, with juniors handling basic SQL queries and seniors excelling in advanced database optimization and NoSQL technologies.
