Ruby on Rails Maintenance & Modernisation

Keep your Rails application secure, maintainable and moving forward.

Senior Rails support for existing applications

Soundlining specialises in taking over mature Ruby on Rails applications, understanding how they work, reducing operational risk and continuing to develop the product without forcing an unnecessary rebuild.

Experience spans many generations of Rails and Ruby, from older legacy applications through modern releases. The work is pragmatic: stabilise first, improve test coverage where needed, upgrade carefully, then keep shipping useful changes.

Common situations

Our Rails app works, but nobody wants to touch it.

We need to upgrade Rails or Ruby.

Our original developer is no longer available.

We are afraid upgrades will break production.

We need continued product development without rebuilding everything.

Technical debt is slowing us down.

Maintenance & modernisation

  • Rails and Ruby version upgrades
  • Gem and dependency compatibility
  • Security vulnerability review and remediation
  • Technical debt reduction and refactoring
  • Automated testing and RSpec coverage before risky changes
  • Performance investigation and database optimisation
  • Background jobs, Sidekiq and scheduled processing
  • Deployment and infrastructure modernisation
  • New feature development and API integration work

The upgrade approach

Older Rails applications usually contain years of valuable business logic. A rewrite is not the default recommendation. The safer path is often to make the current application understandable, test the parts that matter, remove obvious risk and move through upgrades in controlled steps.

That may include dependency audits, temporary compatibility patches, stronger test coverage, staging deployments, database query review, background job cleanup and production monitoring before larger framework changes are shipped.

Rails Health Check / Technical Audit

A focused technical audit gives you a clear picture of the application's current state and the safest next steps before committing to a larger maintenance or modernisation programme.
