Legacy Rails Maintenance
for SaaS Apps

Keep your existing Rails app stable, maintainable, and moving forward. I help SaaS teams support older Ruby on Rails applications with bug fixes, production debugging, upgrades, code reviews, performance work, and ongoing backend maintenance.

Available for US, UK, Europe, Canada, Singapore, and remote-first teams.

Older Rails apps can keep running, but become harder to change

Many production Rails apps still serve customers well, but the codebase becomes difficult to work with over time. Gems get old, tests are missing, background jobs become fragile, deployments feel risky, and small changes start taking longer than they should.

What I help with

Four areas covered on a typical maintenance engagement. Most teams need a mix — the review decides where to start.

A — Maintenance

Ongoing Rails maintenance

  • Bug fixes across the existing codebase
  • Small feature work and incremental improvements
  • Dependency updates and gem hygiene
  • Targeted code cleanup in the high-traffic areas
  • Technical backlog execution at a steady pace
  • Day-to-day production support
B — Stability

Production stability

  • Production logs and error tracker review
  • Investigation of recurring or intermittent bugs
  • Risky workflow review and risk reduction
  • Deployment issue investigation
  • Rollback and release-risk awareness
C — Codebase

Legacy codebase improvement

  • Identifying fragile areas and risky code paths
  • Reducing the blast radius of risky changes
  • Improving maintainability without rewriting
  • Adding targeted tests where they actually matter
  • Documenting unclear or undocumented behavior
D — Infrastructure

Backend infrastructure touchpoints

  • Sidekiq and background job reliability
  • Redis and Rails.cache behavior
  • Database query performance and indexing
  • ActiveStorage and file processing
  • Deployment configuration review

How legacy Rails maintenance usually starts

Most maintenance work starts with a short technical review. I look at the Rails and Ruby version, Gemfile, deployment flow, background jobs, caching, logs, recurring errors, and the areas that feel risky to change. After that, I suggest a practical maintenance path — immediate fixes, risk reduction, upgrade preparation, or ongoing fractional support.

What you get

Concrete deliverables you can act on — not a slide deck.

This is a good fit if

Ways to work together

Three formats. Pick the one that fits — or start with an audit and decide from there.

Audit

One-time maintenance audit

A focused review of your Rails app — risks, dependencies, production issues, and recommended next steps. Delivered as a written report with prioritized findings, useful before deciding on a maintenance plan or a longer engagement.

Project

Focused stabilization project

A short project to fix recurring bugs, improve risky workflows, reduce production issues, or prepare the app for upgrade work. Defined scope, written outcome, fixed timeline.

Ongoing

Monthly fractional Rails support

Ongoing part-time senior Rails help for maintenance, bug fixes, code review, production debugging, and steady backlog execution. Predictable monthly capacity for teams that don't need a full-time hire.
