A Ruby on Rails developer builds and maintains web applications on Rails. Many startups and SaaS products run on Rails, and a strong Rails developer ships features fast while keeping models, tests and background jobs in good shape.
A great Ruby on Rails Developer does not just complete tasks. They own a function that directly frees you to grow. Here is what that looks like in a scaling business:
01Build features across Rails models, controllers and views
02Write and maintain RSpec or Minitest test suites
03Run background jobs with Sidekiq and keep them reliable
04Upgrade Rails and Ruby versions safely
05Find and fix slow queries and N+1 problems
How this hire moves your business forward: Rails is built for small teams shipping quickly. A strong Rails developer keeps that speed as the app grows, instead of letting it slow under technical debt.
