LEGACY APP RESCUE

Ruby on Rails Rescue & Modernization Services

We Stop the Hemorrhage.

Slow deployments. Scary releases. Developers afraid to touch the code. Sound familiar? We specialize in rescuing Ruby on Rails systems that have become liabilities instead of assets.

THE HIDDEN COST

What legacy Rails really costs you

Deployment paralysis

Every release feels like Russian roulette. Your team spends more time fixing than building. New features take 3x longer than they should.

The "Don't Touch It" Syndrome

Nobody wants to change that critical module because "everything might break." Your codebase has become a hostage situation.

Developer churn

Good developers don't want to work on legacy systems. You're stuck with whoever will accept the job, or paying premium for scarce Rails talent.

Rails upgrade pressure

You're 3-4 versions behind. Security patches are getting harder. Every month you delay makes the eventual upgrade more expensive.

OUR RESCUE SERVICES

How we bring your Rails app back to life

Emergency stabilization (Rescue Sprint)

When things are on fire. We come in, diagnose the critical issues, and implement a recovery plan. Within 2-4 weeks, your deployments become boring again.

  • Critical bug triage
  • Emergency performance fixes
  • Deployment pipeline stabilization
  • Documentation of hidden dependencies

Incremental modernization

We upgrade your Rails app without the big-bang rewrite. Using the "Strangler Fig" pattern, we modernize piece by piece while the system keeps running.

  • Rails version upgrades (even from 4.x)
  • Ruby version updates
  • Gem dependency cleanup
  • Test coverage restoration

Performance resurrection

Your app was fast once. We make it fast again. Database query optimization, N+1 elimination, caching strategies that actually work.

  • Database query audit
  • Background job optimization
  • Memory leak detection
  • Scalability roadmap

Knowledge transfer & documentation

The original developers are gone. Tribal knowledge is lost. We reverse-engineer your system and create documentation your team can actually use.

  • Architecture documentation
  • Runbooks for operations
  • Onboarding guides for new developers
  • Technical debt inventory
