    A note from our founder

    I'm not a Rails developer, but I have delivered a lot of Rails projects

    I came up writing C#, not Ruby. That side of our bench has its own team for clients who want .NET development services. So when I tell you Full Scale delivers great Ruby on Rails development services, I am not basing that on twenty years of writing ActiveRecord. I am basing it on the Rails projects we have staffed at SaaS companies, and on the Rails platform we built for RealQuantum, a commercial real estate appraisal company that used Full Scale to grow their product engineering team.

    Full Scale is a Ruby on Rails development company built around senior Filipino developers and the Product Driven framework. Every Rails project we deliver goes through staff augmentation: engineers join your team, work your hours, commit to your repo, and own what they ship. We test them on real applications, not coding-bootcamp questions, and we keep them on the bench long enough to know how each one actually thinks. If you are serious about offshore Ruby on Rails development services that ship real product, you are in the right place.

    Why Ruby on Rails for this project

    Five reasons Rails is the right stack for product velocity

    If you've already committed to Rails, you don't need to read this. If you're still evaluating whether Rails is the right call for your project, or whether to migrate an existing system toward it, these are the technical arguments that hold up in production, not in a vendor slide deck.

    Convention over configuration ships faster

    Rails' opinionated defaults mean far less boilerplate and far fewer decisions per feature. For CRUD-heavy products and MVPs, a Rails team gets to a working, deployable app faster than almost any alternative. That velocity is the whole point, and it compounds when the team shares the same conventions.

    Batteries included, hardened over 20 years

    ActiveRecord, ActionCable, ActiveJob, Hotwire, and a mature gem for nearly every problem ship in or near the box. Two decades of production use mean the sharp edges are documented and the patterns are settled, so your team builds product instead of plumbing.

    Built for product velocity

    Rails' sweet spot is business applications and SaaS where time-to-feature matters more than squeezing microseconds. GitHub, Shopify, and Basecamp run on it at serious scale. The honest caveat: for CPU-bound or massive-concurrency workloads, we'll point you at Go or Elixir instead.

    A cohesive framework with a strong testing culture

    One idiomatic way to do most things, plus a community that takes testing seriously (RSpec, Minitest, factory_bot, system specs). That cohesion keeps a large Rails codebase legible and keeps new engineers productive quickly.

    Proven at scale, and a safe long-term bet

    Rails is mature, actively maintained, and still shipping major versions with real improvements. For a product you'll run for years it's low-risk. The trade-off to weigh honestly is talent: the Ruby hiring pool is smaller than JavaScript or Python, which is exactly why a vetted offshore bench matters here.

    Built different

    AI-powered Rails engineers, trained on Product Driven principles

    Rails codebases age on a knife's edge. Kept conventional and tested, a Rails app is one of the cheapest systems in software to maintain; let entropy in, and the same app becomes the legacy monolith nobody wants to touch. AI-generated code accelerates whichever direction you're already headed.

    That's the actual job of a Rails development service: not just shipping features, but keeping the app on the cheap side of that line while it grows. Our engineers are trained on the Product Driven approach from Matt's book and the full modern AI toolkit, and the combination is what keeps year-five Rails codebases moving at year-one speed.

    Pillar 1

    Convention-keepers, not code generators

    A Rails app stays cheap to change exactly as long as it stays conventional. The expensive Rails codebases are the ones where every corner solves the same problem a different way. Our engineers treat the conventions as the asset they are: new work reads like the framework intended, models stay skinny, and the app a new engineer opens in year three still makes sense in an afternoon.

    Read Product Driven, the book
    Pillar 2

    AI that respects your codebase

    Rails is the framework AI assistants generate best, precisely because of its conventions, and that cuts both ways: the tools will also happily produce code that fights your app's patterns and compounds into entropy. Our engineers use Copilot, Claude, and Cursor daily for scaffolds, RSpec coverage, and migrations, with the human judgment call on every merge: does this belong in this codebase, written this way.

    Rails rewards engineers who think before they type. The framework already has an opinion about almost every problem you will face, so the question is whether your developer knows which opinion to follow and which one to fight. The Rails developers I want on my team know the difference, and they use AI to handle everything that doesn't.

    Ruby on Rails development services we deliver

    Ruby on Rails development services delivered through your team, not around it

    What kind of Rails work do you need done? A greenfield SaaS build, an API-only service for your React frontend, a Rails upgrade from version 5 to version 8, a performance fix that has been open for six months? Every service below is delivered through staff augmentation: senior Filipino Rails engineers join your team and work under your direction, billed for engineering hours rather than fixed-bid projects. As a Ruby on Rails development company, we ship across all of it. Here are the Rails development services we get hired for most often.

    Custom Ruby on Rails development

    Custom Rails development means greenfield builds on modern Rails 7 or Rails 8, using Hotwire, Turbo, Stimulus, and View Components where they fit. We start with a real domain model rather than a scaffold dump, so the resulting codebase still makes sense to your team eighteen months in.

    Read our Rails outsourcing guide

    Rails SaaS development

    Multi-tenant SaaS on Rails is our home turf: account scoping, role-based access with Pundit, subscription billing with Stripe, audit trails, and the boring infrastructure that paid SaaS lives on. The Rails Way for SaaS, without reinventing the wheel.

    Rails API development & system integration

    We build Rails API-only services with proper serialization, versioning, and OpenAPI contracts. Third-party integrations get circuit breakers, retry logic, and idempotency keys, which gives you an API your downstream consumers don't curse at.

    Hire offshore API developers

    Rails deployment and DevOps

    We deploy Rails to Heroku, Render, Fly.io, AWS, and self-hosted Kubernetes. CI runs in GitHub Actions or CircleCI with parallelized RSpec, Brakeman scans, and proper review apps. Releases are boring in the good way.

    Legacy Rails upgrades and modernization

    We run production Rails upgrades from Rails 5 to Rails 7 or 8 without downtime. We know which gems break in an upgrade, where Spring and Bootsnap will fight you, and how to stage the cutover so business doesn't stop. This is Rails modernization work we have done for systems with millions of users.

    Read about Rails pros and cons

    Rails performance and debugging

    Our Rails performance work covers Skylight and New Relic profiling, Bullet for N+1 detection, jemalloc tuning, and database index work in PostgreSQL. These are skills most offshore Rails shops never developed, so hire us when your application is slow and nobody knows why.

    How we architect Rails systems

    Architecture patterns our Rails engineers apply in production

    Most offshore Rails shops deliver a working application at handoff. What determines whether it's still working and maintainable 18 months later is the architecture decisions made in the first sprint. These are the patterns our engineers reach for, and the reasoning behind when each one earns its complexity.

    The Rails Way + Service Objects

    Skinny controllers, models that own their data, and service objects (or interactors) when business logic outgrows a model. We follow Rails conventions instead of fighting them, and extract structure only when the domain earns it.

    Service ObjectsConcernsPOROs

    Modular Monolith with Packwerk

    A well-bounded monolith beats premature microservices for most Rails apps. We use Packwerk to enforce package boundaries inside the monolith, so the codebase stays modular and the team can reason about it without distributed-systems overhead.

    PackwerkDomainsBoundaries

    Background Jobs & Async

    Heavy or slow work moves off the request path onto Sidekiq or Active Job. Jobs are idempotent and retry-safe, queues are prioritized, and we don't block a web worker on a third-party API call. This is how a Rails app stays responsive under load.

    SidekiqActive JobIdempotent

    API-Only + Decoupled Frontend

    When the frontend is React or Vue, Rails runs in API-only mode with fast JSON serializers (Oj, Alba) and versioned endpoints. When server-rendered is the better fit, Hotwire and Turbo keep it snappy without a separate SPA. We pick per project.

    API modeHotwireSerializers

    Performance: N+1, Caching, Indexes

    The N+1 query is the number-one Rails performance killer, so we catch it with Bullet and eager loading, add the database indexes ActiveRecord won't add for you, and layer fragment and Russian-doll caching where it pays. Profiled, not guessed.

    BulletEager LoadingCaching

    Testing & CI

    RSpec or Minitest with factory_bot, request specs for the API surface, and system specs for the critical flows, all running on a CI pipeline fast enough that people actually wait for it. A Rails app without a real test suite rots quickly, so this is non-negotiable.

    From the engineering team

    Opinionated takes on Rails from engineers who ship it

    Most vendors tell you Rails is the right choice for everything. We'll tell you when it isn't. These are the actual opinions we hold based on building and maintaining Rails systems in production, not talking points from a sales deck.

    When we'd recommend Rails

    CRUD-heavy SaaS, MVPs that need to reach the market quickly, and business applications where convention and developer productivity matter more than squeezing the runtime. If you want a small team to ship a lot of product fast, Rails is still one of the best bets going.

    When we'd recommend something else

    CPU-bound or massive-concurrency workloads, where Go or Elixir handle the load Ruby struggles with. Machine learning and data work, which belong in Python. Ultra-low-latency systems. And if your local hiring market for Ruby is thin and you can't staff offshore, the smaller talent pool is a real risk we'll name rather than gloss over.

    Patterns we ship vs. patterns we refuse

    We ship service objects for logic that outgrows a model, real RSpec coverage, eager loading to kill N+1, idempotent Sidekiq jobs, and Sorbet types where they earn their keep. We refuse fat controllers, callback soup in models that nobody can trace, N+1 queries left to rot, business logic stuffed into views, and monkey-patching core classes for convenience.

    Rails migrations we've seen go wrong

    Teams that skipped multiple major versions and then tried to jump Rails 4 to 7 in one release. Apps stranded on an end-of-life Ruby because the test suite was too thin to upgrade safely. Premature monolith-to-microservices splits that added ops cost without payoff. And asset-pipeline migrations (Sprockets to Propshaft or importmaps) that got half-done and left the build in a fragile state.

    How we deliver

    From first call to production: how a Rails project runs at Full Scale

    Staff augmentation without a delivery framework is just headcount. Here is what the engagement actually looks like from the first conversation to a deployed production system and the ongoing work that comes after.

    01
    Discovery & scoping
    Days 1–3

    We scope the engagement together: what to build first, what specializations to staff, what the first sprint should deliver. You walk away with a staffing plan and a candidate shortlist, not a 40-page requirements document.

    Staffing plan
    Sprint 1 scope
    Candidate shortlist
    02
    Engineer selection & onboarding
    Days 3–7

    You interview our pre-vetted candidates and select who starts. We handle employment, payroll, and equipment setup on the Philippines side. Your engineer gets access to your repo, your tools, and your standups. First commit typically happens within the first week.

    03
    Iterative sprint delivery
    Ongoing

    Your engineer works in your sprint cadence, under your tech lead, committing to your repo. You see the work in progress, not at a scheduled demo. Architecture decisions happen in your standups, not behind a project management wall. The sprint velocity is yours to direct.

    Quality & testing
    Built into every sprint

    Our engineers write tests as part of delivery, not as a post-sprint cleanup task. RSpec or Minitest with factory_bot, request specs for the API surface, and system specs for critical flows. AI-assisted PR review (Copilot, Cursor) before human review. Code that ships is code that's been tested.

    Automated test suites

    Deployment & production ownership
    At launch and beyond

    Your engineers own the production deployment: infrastructure as code, observability from day one (Sentry, New Relic, or equivalent), and runbook documentation for the most likely failure modes. They stay on after launch. Post-launch bugs go into your backlog like any other work, not into a 'warranty period' clause in a contract.

    How a Rails engagement actually starts

    No RFP theater and no 3-6 week recruiting cycle. The bench is already vetted, so the open questions are about your app, not our pipeline: what you're building, what state the codebase is in, and what team shape the roadmap needs.

    01

    Discovery call

    Day 1

    30 minutes on your product and your Rails situation: greenfield build, feature velocity on a live app, or an upgrade/rescue. You leave with a straight read on what the engagement should look like and what it would cost.

    02

    Scope the work, shape the team

    Days 2-3

    We translate the roadmap into a team shape: how many engineers, which specializations (API, Hotwire, DevOps), and where the first month goes. For existing codebases this includes a read of the app's version, test coverage, and upgrade debt.

    03

    Meet the engineers

    Days 3-5

    We propose pre-vetted Rails engineers matched to that plan, and you interview them yourself: live coding, system design, ActiveRecord judgment, whatever convinces you. Pass on anyone you don't believe in.

    04

    One contract, zero offshore admin

    Days 5-6

    Sign once with Full Scale. We employ the engineers in the Philippines and carry payroll, equipment, benefits, and HR, so you get a Rails team without managing an offshore entity.

    05

    Work underway

    Day 7

    The team joins your standups, gets repo and CI access, and ships in week one, whether that's the first feature branch or the first upgrade PR. A client success manager stays on the account so ramp-up doesn't stall.

    Why outsourced Rails projects go bad

    The demo works. The codebase is the deliverable

    Rails development services fail in a predictable pattern: the vendor optimizes for the milestone demo, and the things that make a Rails app cheap to run for five years, query discipline, job infrastructure, upgrade hygiene, get skipped because no milestone measures them. These six are the gaps we're hired to fix most often, so we build our own engagements around not creating them.

    Projects scoped as features, delivered as debt

    Outsourced Rails projects usually get judged on whether the feature works at the demo. The real cost shows up in how it was built: abstractions the app didn't need, conventions ignored, and a codebase the next engineer fights. Our engagements are judged on the state of the app, not just the demo.

    Query problems that surface after launch

    The most common Rails services failure we clean up: an app delivered working at demo-data scale that melts at production scale, because nobody watched the query patterns. N+1s, missing eager loading, and unindexed lookups are checked during development in our engagements, not discovered by your customers.

    Background jobs treated as an afterthought

    Vendors ship the happy path and leave Sidekiq queues, retries, and idempotency for later. Later is when a stuck queue silently drops customer emails for a week. Job infrastructure is part of the definition of done in our Rails work, because that's where production incidents actually come from.

    Upgrades nobody budgeted for

    A Rails app pinned to an old version accumulates risk quietly: gems stop getting patched, hosting options narrow, hiring gets harder. Our engagements keep the upgrade path part of the ongoing work, walking versions forward incrementally instead of leaving you a Rails 5 time bomb.

    Security assumed instead of verified

    Rails gives you good defaults, and vendors love to assume that's enough. Auth flows, authorization policies, mass assignment guards, and credentials handling still have to be built and reviewed deliberately. Security review is a standing part of our delivery, sized to what your product actually exposes.

    Nobody watching production

    A development service that ends at deploy leaves you alone with the 2 a.m. page. Our engineers read the Skylight and New Relic traces, profile the hot endpoints, and treat production behavior as feedback into the next sprint, because they're still on the team when the pager goes off.

    Rails development services by industry

    Rails expertise tuned to your industry

    As a Ruby on Rails development company that has been around for over a decade, we have placed dedicated Rails developers into nearly every industry that runs on the framework. Domain knowledge cuts onboarding time in half, so we match developers to projects where they have already shipped real code.

    SaaS & Scale-ups

    B2B SaaS on Rails is our home turf, with engineers who have shipped multi-tenant architecture, subscription billing with Stripe, role-based access with Pundit, and white-label theming. Rails was built for SaaS, and the bench has the years to prove it.

    How to hire dedicated Ruby on Rails developers

    Hire dedicated Rails developers, two ways

    Most clients start with a single dedicated Rails developer and grow into a full team. Either way, you get full-time engineers who sit on your standups, work your hours, and ship code against your roadmap. Both options are the staff augmentation model at the core: dedicated, long-term engineers embedded in your team rather than freelancers, shared resources, or a project shop on the side. See the full breakdown of how we hire dedicated Ruby on Rails developers across every engagement we staff. When a feature spans both the Rails backend and a React or Hotwire frontend, you can hire dedicated full-stack engineers from the same bench.

    Dedicated developer

    Full-time, exclusive, sits on your standups.

    Best for
    Long-running products with a real roadmap.
    What's included

    • Works your hours, your tools, your codebase
    • Joins your standups, reports to your tech lead
    • We handle payroll, HR, equipment, retention
    • Two-week money-back guarantee

    Dedicated team

    Multiple engineers, embedded as a pod.

    Best for
    New product builds, full-stack feature pods.

    Pricing

    Dedicated Ruby on Rails developers, starting at $35 an hour

    That rate is fully loaded. Every engineer we staff on your Rails project is a senior developer in the Philippines working full-time under your direction, and we cover the payroll, benefits, HR, and equipment. The same role hired locally in the US costs $150K to $195K a year, which is the delivery math that brings most teams to the table.

    Trusted operator

    Full Scale has made the Inc. 5000 four years in a row and is Great Place to Work certified. We have been doing this since 2018, and pricing isn't the only reason clients stay with our Ruby on Rails development company, it's the easiest reason to call.

    Why the Philippines

    Why we deliver Rails projects from the Philippines

    Every Rails project we deliver is staffed from the Philippines. You can also hire dedicated developers in the Philippines across every other stack we work in, with the same vetting bar, retention, and engagement model that Rails clients get.

    English-fluent by default

    The Philippines is the third-largest English-speaking country in the world. Standups, code reviews, and customer calls work the way they do with any US team member.

    Real time-zone overlap

    Most of our Rails engineers shift their hours toward the US business day, giving 3-4 hours of real-time overlap with East and West Coast teams, so decisions happen live during shared hours rather than crawling through 24-hour async handoffs.

    Deep engineering talent pool

    Cebu and Manila produce tens of thousands of CS and IT graduates a year, deep enough to staff a full Rails project team without compromising on seniority. The Philippines has been a serious Rails offshore market since the framework went mainstream.

    Cultural alignment with US teams

    Filipino engineers grow up on US business norms, US TV, and US tech culture, so agile rituals, direct feedback, and collaborative workflows feel familiar from day one. These teams integrate fast rather than needing constant management.

    How we compare

    Full Scale vs the other ways to hire a Rails developer

    Every hiring path has trade-offs. Here is how a dedicated Rails engineer from our Ruby on Rails development company compares against the alternatives most teams consider first when they want to hire Rails developers.
