FAQ
What versions of Ruby on Rails do you work with?
I work with Rails 6, Rails 7, and Rails 8, covering both legacy Rails applications and modern greenfield projects. Whether you need an upgrade or a fresh Ruby on Rails build, I've got you covered.
Can you build and integrate RESTful APIs in Ruby on Rails?
Yes! I specialize in building and maintaining RESTful APIs using Ruby on Rails, including serializers, API documentation, and seamless third-party API integrations such as payment gateways, authentication providers, and external services.
Do you write tests for your Ruby on Rails code?
Absolutely. I write clean, maintainable test cases using RSpec, following both TDD (Test-Driven Development) and BDD (Behavior-Driven Development) approaches to ensure your application is reliable and production-ready.
Can you fix bugs or improve an existing Rails application?
Yes. I offer bug fixing, code refactoring, and performance optimization for existing Ruby on Rails applications. I also conduct thorough code reviews to improve architecture, readability, and long-term maintainability.
Do you handle frontend work alongside Ruby on Rails backend development?
Yes. I provide full-stack Ruby on Rails development, including pixel-perfect UI implementation using HTML, CSS, and JavaScript, along with modern Hotwire and Turbo Streams integration for dynamic, fast-loading interfaces.
