Ruby on Rails Consulting & Application Support

Need help with an existing Ruby on Rails application?

How I can help

01 / Rails Application Consulting

Ruby on Rails application audit

Technical analysis of an existing Ruby on Rails application.

I can review your application's architecture, codebase, dependencies and development setup to identify technical risks, outdated components and areas that may make future development harder.

This is useful when you have inherited an existing Rails application, are preparing a new development phase, or simply need an experienced Rails developer to evaluate the current state of the system.

Typical areas I review:

  • Rails and Ruby versions
  • application architecture
  • dependencies and outdated gems
  • database structure
  • background jobs and integrations
  • tests and test coverage
  • performance and maintainability
  • deployment and infrastructure
02 / Legacy Ruby on Rails Support

Keep an older Rails application running reliably.

I help teams maintain Ruby on Rails applications that are running on older versions of Ruby, Rails or their dependencies.

If your application is stable but difficult to maintain, upgrading everything at once may not be the right approach. I can help assess the current situation, identify risks and plan incremental improvements without unnecessary rewrites.

I can help with:

  • legacy Ruby on Rails applications
  • outdated Rails versions
  • outdated Ruby versions
  • old or unsupported gems
  • dependency compatibility issues
  • incremental modernization
  • technical debt analysis
  • maintenance and troubleshooting
03 / Rails Dependency & Security Updates

Keep your Ruby on Rails application's dependencies up to date.

Outdated gems and framework dependencies can introduce security vulnerabilities and make future upgrades increasingly difficult.

I can help review your application's dependency tree, identify outdated or vulnerable dependencies, and update them while keeping compatibility with the existing application.

This can include:

  • Ruby and Rails security updates
  • gem dependency updates
  • dependencies affected by known CVEs
  • Bundler dependency resolution
  • compatibility fixes after updates
  • regression testing
  • identifying dependencies that require a larger upgrade
Fit

Who this is for

This service can be useful if:

  • you inherited a Ruby on Rails application from another developer or team;
  • your application runs on an old version of Rails or Ruby;
  • your security team identified vulnerable dependencies or CVEs;
  • your team needs help evaluating an existing Rails codebase;
  • you are planning a Rails upgrade and need a technical assessment first;
  • development has slowed down because of technical debt;
  • you need temporary senior Rails support for an existing product.
Process

How it works

01 — Understand

We discuss the application, the current problem and what you want to achieve.

02 — Analyze

I review the relevant parts of the codebase, Rails/Ruby versions, dependencies and architecture.

03 — Recommend

You receive a clear assessment of the current situation and recommended next steps.

04 — Implement

If needed, I can continue with the actual fixes, upgrades or ongoing maintenance.

Have an existing Rails application that needs attention?

Tell me what you are dealing with — an old Rails version, vulnerable dependencies, technical debt, an upcoming upgrade or simply a codebase that needs an experienced second opinion.
