How much does it cost to hire Ruby on Rails developers?
Cost depends on the engagement: a new Rails application, an upgrade, a rescue of an existing codebase or dedicated developers working inside your team. DevLunch does not bill by the hour. Each engagement is priced per fixed 6-week cycle, with price and deadline set before development starts.
Before a cycle starts, the work is shaped with you: the problem, the appetite (how much it is worth) and a solution outline. At the end of the cycle, working software is in production. You decide after each cycle whether to continue.
Is Ruby on Rails still a good choice for a new web application?
Yes, for most business web applications: B2B portals, marketplaces, SaaS products, back offices, ecommerce platforms and internal tools. Rails includes the database layer, background jobs, email, file uploads, caching and an authentication generator, so a small team ships complete features in each cycle.
With Hotwire (Turbo and Stimulus), Rails delivers interactive interfaces without a separate JavaScript frontend to build and maintain. When a project also needs a mobile app or a React frontend, Rails serves the JSON API behind it.
How do you upgrade an old Rails app?
Upgrades go one step at a time: Ruby version, Rails version, then gems. Each step runs the test suite, fixes deprecation warnings and ships to production before the next one starts. Where tests are missing, they are added around the critical flows first.
Typical upgrade work: moving from Rails 5, 6 or 7 to Rails 8, replacing abandoned gems, moving off Webpacker to importmap or jsbundling, replacing Rails UJS and jQuery with Hotwire, and moving background jobs from Resque or Delayed Job to Sidekiq or Solid Queue.
Can you take over a legacy Ruby on Rails application?
Yes. Rescue projects start with a code review: Ruby and Rails versions, test coverage, dependencies, security advisories, slow pages and the deployment setup. The result is a list of problems ranked by risk, and a first cycle shaped around the most urgent ones.
Common rescue work: fixing slow pages and N+1 queries, moving long tasks to background jobs, stabilizing deploys with Docker, patching security issues, and documenting the app so more than one developer can work on it.
Ruby on Rails developers in the Dominican Republic
DevLunch builds Rails applications in Santo Domingo for companies in the Dominican Republic and the United States, plus US agencies. Rails runs the asi.do B2B ecommerce platform and wholesale quote system (in production since 2021), the Contrata.com home services marketplace (since 2018), the Fancy Sinner ecommerce and subscription box platform (launched January 2026) and Recibos.do, a SaaS for Dominican businesses and accounting firms (launched May 2026).
Engagement options: fixed-price builds by cycle, dedicated Rails developers (staff augmentation) working in your repository and process, and maintenance and support for Rails apps already in production. The client owns the repository and code from day one.
