Ruby on Rails specialists for your dedicated team.

When a Rails product needs experienced developers.

Many Rails products are ten years old and still earn most of the company's revenue. The founders' code is in there, the test suite is slow and the app runs a Rails version that no longer gets security fixes. That is the moment to add developers who have upgraded Rails before.

Growth is the other trigger. Pages slow down as tables pass tens of millions of rows, background jobs pile up in Sidekiq, and one PostgreSQL database carries everything. Rails can go much further, as Shopify and GitHub show, but it takes deliberate work on queries, caching and job design.

Sometimes the trigger is a frontend decision. A team that added a React single-page app to Rails may find that Hotwire, with Turbo and Stimulus, handles most screens with far less code. Choosing which screens to move takes someone who knows both.

What our Ruby on Rails developers work on.

• Version upgrades Moving an app one minor version at a time, for example from 7.0 to 7.1, 7.2 and then 8.0. Deprecation warnings are fixed at each step, and the test suite runs against both versions.
• Query work Finding N+1 queries with Bullet or strict loading, adding indexes, and writing migrations for large tables that run without downtime.
• Background jobs Writing idempotent Active Job classes on Sidekiq or Solid Queue, with retries and queue priorities set on purpose.
• Hotwire screens Building interactive pages with Turbo Frames, Turbo Streams and Stimulus where a full JavaScript framework isn't needed.
• Untangling models Moving business logic out of callbacks and thousand-line models into plain Ruby objects with their own tests.
• Safety net Raising RSpec or Minitest coverage on the paths that earn money, and running RuboCop, Brakeman and bundler-audit in CI.

Rails rewards developers who know one codebase deeply. Companies that hire dedicated developers through us get Rails developers who work on one product only. Our people stay with us for 3.3 years on average, so that knowledge builds up.

Where Rails codebases get expensive.

Callbacks are the classic trap. Saving a record quietly sends an email, updates three other tables and calls an API. Each one made sense on the day, and together they make every change risky. Good Rails developers keep callbacks for data integrity and put workflows into explicit service objects.

Falling behind on upgrades costs more each year. Gems drop support for old versions, security patches stop and the jump gets bigger. A team that upgrades with each minor release avoids the big one.

Tests that are slow or flaky get skipped. A suite that takes forty minutes and fails at random protects very little. Removing shared state and heavy factories makes it fast enough to run on every commit again.

Questions about Rails developers.

• Is Rails still a good choice in 2026? For most web products, yes. Rails 8 ships with background jobs, caching and WebSockets that run on the database, a deploy tool called Kamal and Hotwire for the frontend. A small team can run a full product with few moving parts. It is a weaker fit for heavy data science or hard real-time systems.
• Should we rewrite our old Rails app? Rarely as a first step. A rewrite pauses feature work and brings back bugs the old code fixed long ago. Upgrading Rails, raising test coverage and splitting the worst models gives most of the benefit while the product keeps shipping.
• Can offshore Rails developers work with our in-house team? Yes. They join your standups, your pull requests and your Slack or Teams channels, and you set the priorities. Thailand is five hours ahead of Northern Europe in summer and six in winter, so a European morning overlaps with the Thai afternoon.
