Ruby on Rails development services
Ruby on Rails development services for web applications, SaaS products, online shops and marketplaces, APIs for web and mobile clients, Hotwire Native apps, and the upgrade and take-over of long-lived Rails codebases, with dedicated Ruby on Rails developers for your team or a Rails project delivered end to end.
What we build with Ruby on Rails
Rails applications
Full-stack web applications on current Rails with Hotwire (Turbo and Stimulus) for interactivity, ViewComponent for reusable screens, and the built-in authentication generator or Devise for sign-in.
Rails APIs
JSON APIs in Rails API mode or GraphQL through graphql-ruby, for React, Vue and mobile clients, with validation at the edge and an OpenAPI description generated by rswag.
SaaS products on Rails
Multi-tenant products with acts_as_tenant or a schema per tenant, subscription billing through the Pay gem with Stripe or Paddle, and roles enforced in Pundit policies.
Shops and marketplaces on Rails
Solidus or Spree stores, multi-vendor marketplaces, and Shopify apps built on Shopify’s Rails app template, with payments, stock and orders kept in step with the systems around them.
Background jobs
Sidekiq or Solid Queue workers for imports, emails, billing runs and webhooks, with retries, uniqueness and alerts, so a failed job is visible rather than silently dropped.
Rails upgrades
Older Rails and Ruby versions moved forward one release at a time, with deprecation warnings cleared, dual booting where it helps, and tests added ahead of each step.
Inherited Rails applications
Rails applications whose original team has left, starting with a read-only review of the code, the gems and the hosting, and a written list of risks in order of impact.
Rails performance tuning
Slow endpoints traced with rack-mini-profiler or your APM to the query behind them, N+1 queries caught by strict loading, caching with Solid Cache where it is safe, and YJIT switched on.
Hotwire Native mobile apps
iOS and Android apps that reuse the Rails screens through Hotwire Native, with native screens only where the app needs them, so one team ships web and mobile together.
Hire Ruby on Rails developers
Dedicated Ruby on Rails developers
Ruby on Rails developers who join your team full time, work in your repositories, tracker and meetings, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.
Ruby on Rails project delivery
A team that takes the Ruby on Rails project from scope to release: estimate, build, tests and deployment, with a technical lead on our side who owns the plan and the quality.
Ruby on Rails support and take-overs
An existing Ruby on Rails system taken over from another team or kept running: a read-only review and a written list of risks first, then fixes and new features in order of impact.
The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.

How we work on Rails
Current Rails and Ruby releases, strong parameters and authorisation on the server, every query through Active Record rather than string interpolation, Brakeman and bundler-audit in the pipeline, security advisories treated as unconditional upgrades, and tests that ship with each feature. Deployment through Kamal, Heroku or Render, or to containers on Azure or AWS with the infrastructure as code.
Developers work in your repositories, your tracker and your process. The Ukrainian contract, payroll, invoicing and leave stay with us, and everything they write is assigned to you.

Questions about Ruby on Rails development
Which industries do your Ruby on Rails developers work in?
E-commerce and SaaS first: shops, marketplaces, subscription products and the business software behind them. Then fintech, with lending, accounting and payment back offices; healthcare, with patient portals, scheduling and practice management; education, with learning platforms and course marketplaces; and property, with listing, rental and property management platforms.
Can you upgrade our old Rails application?
Yes, one Rails version at a time, each step released on its own, with deprecations cleared and tests added before anything moves.
Can you take over a Rails application whose team has left?
Yes. A take-over starts with a read-only review and a written list of risks in order of impact, before anyone changes a line, so you know what you have before you decide what to do with it.
How quickly can Ruby on Rails developers start?
When the right Ruby on Rails developer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.
How do we hire Ruby on Rails developers through BigTree108?
Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.
Who owns the work they produce?
You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.
Running a Rails application?
Tell us the Rails version and what needs doing. You get an answer within one business day: candidate profiles or a plan for the upgrade.
