About Ruby on Rails
What You Actually Get With Ruby on Rails
Rails is an opinionated full-stack framework. MVC, an ORM, migrations, a job queue, mailers, WebSockets and file storage all ship together and all agree with each other, so the first week goes on features rather than on choosing a router, an ORM and a test runner that have never met.
The payoff compounds. Because every Rails app is laid out the same way, a developer who has worked on one can read yours — models here, jobs there, migrations in order. That is the real reason three people can carry a product that would need a larger team on a stack assembled from parts.
It is not free, and we would rather say so on the way in. Ruby is slower per request than a compiled runtime, so CPU-heavy work belongs in a job or another service. Active Record makes N+1 queries easy to write and easy to miss. An app that skips two major upgrades gets expensive to rescue. We plan for all three from the first sprint: jobs early, query counts asserted in tests, and upgrades treated as maintenance instead of a project.
What our Rails team brings
- Active Record and migrations
- Hotwire instead of a second stack
- Sidekiq for slow work
- PostgreSQL as the default store
- RSpec suites that run in CI
- Version upgrades on a schedule

What We Build With Ruby on Rails
06Rails service lines
CMS Development
Editorial tools built on Action Text, Active Storage and your own models, rather than bent around someone else's plugin ecosystem. Editors get a workflow that matches how they actually publish, and you keep a schema you can query and report on.
- Draft, review and publish states
- Multi-locale content
- Image and document handling
- Rails
- ActionText
- Active Storage
Rails Architecture Consulting
A careful read of the codebase before anyone proposes a rewrite. We look at query counts per endpoint, what the job queue is really doing, where the tests are thin, how far behind Rails you are and which gems are unmaintained — then hand back a ranked list with the cost of each item.
- N+1 and slow query audit
- Rails and gem version review
- Ranked remediation plan
- Architecture
- Code Review
- Performance
Upgrades and Rails Migrations
Upgrading an app that is two majors behind is mostly dependency archaeology and deprecation work. We do it one version at a time behind a green test suite, replacing abandoned gems before the framework moves rather than after, so each step can be shipped and judged on its own.
- One major version at a time
- Gem replacement plan
- Staged cutover with rollback
- Rails 7.1
- Migrations
- CI/CD
Deployment and Integrations
Third-party APIs get their own adapter layer, so swapping a payment or messaging vendor is a class change instead of a refactor. Deploys run from CI, and migrations are written so the old code and the new schema can coexist while a release rolls out.
- Adapters around third-party APIs
- CI-driven deploys
- Backward-safe migrations
- Docker
- Heroku
- AWS
Rails Commerce Builds
Spree or Solidus when your catalogue fits their model, a plain Rails domain model when it doesn't — a decision worth making early, because it is painful to reverse. Checkout, payments, inventory and order state carry the heaviest test coverage in the app, because that is where money goes missing.
- Payments and webhook replay
- Inventory and order state machines
- Checkout tested under load
- Spree
- Solidus
- Stripe
Ongoing Care and Fixes
Someone who knows your app watches the error tracker, the queue depth and the slow query log, and keeps Ruby, Rails and gems moving so an upgrade never turns into a project. Cover and response times are agreed per engagement rather than promised in the abstract.
- Error and queue monitoring
- Security patches and gem bumps
- Small feature work between releases
- Monitoring
- Upgrades
- DevOps

Why Ruby on Rails
Ten Things That Keep Teams On Ruby on Rails
Not marketing points. These are the reasons engineers who have shipped on other stacks keep coming back to this one.
One Way to Lay Things Out
Models, controllers, jobs and migrations sit where every other Rails app puts them. Onboarding costs days rather than weeks, because a new developer already has the map.
Testing Is Wired In
Fixtures, a test database, system tests and a runner ship with the framework. The default is a suite that runs, which is a large part of why Rails apps tend to have one at all.
Readable Six Months Later
Ruby reads close to prose and Rails leans on that. You can open a model, read a callback and know what it does without tracing three layers of indirection first.
Generators for the Routine Parts
One command gives you a migration, model, controller and tests. Useful for the routine half of an app, and worth throwing away the moment the domain gets interesting.
Fast to a First Version
Auth, mail, uploads, jobs and WebSockets are decisions already made. A working product exists early, which is when you find out whether it was the right product.
A Gem for Most Problems
Authentication, authorisation, queues, payments — the common problems have a well-worn answer. The discipline is adding fewer of them, because every gem is a future upgrade.
Scales in the Usual Ways
Stateless app servers behind a load balancer, PostgreSQL with read replicas, Redis for cache and queues. The ceiling is almost always the database, not the framework.
A Community That Maintains Things
Rails is old enough that the answers exist and active enough that they are still current. Security releases are prompt and the upgrade guides are honest about what breaks.
Hotwire Instead of a Second Stack
Turbo and Stimulus cover most interactivity without a separate frontend app, build pipeline and API layer. When a screen genuinely needs React, you can add it to that screen alone.
Fewer People for the Same Product
The cost argument for Rails is not cheap developers. It is that a small team can hold the whole system in their heads, so less of the budget goes on coordination.
Why Hire Aryavos
What Working With Us Looks Like
Small Increments
Work ships in short cycles behind feature flags. You see the product move every week, and we find out early when a specification was wrong — which is cheaper than finding out at the end.
Tests Where They Pay
Domain logic, money paths and background jobs get thorough coverage, including assertions on query counts. We do not chase a coverage percentage across view templates.
Jobs Before They Are Urgent
Anything that calls a third party or touches many rows goes to the queue the day it is written, with retries and idempotent handlers, rather than after the first production timeout.
Upgrades as Routine Work
Ruby, Rails and gem versions get bumped on a schedule while the diffs are still small. An app that stays close to current never reaches the point where a rewrite looks reasonable.
We Say When Rails Is Wrong
If the workload is CPU-bound, streaming-heavy or genuinely better served elsewhere, we would rather tell you in week one than build the wrong thing carefully.

Development Process
How a Rails Build Actually Runs
Five stages, with the decisions that are expensive to reverse made in the first one.
This stage is spent on the things that are expensive to change later: the data model, whether the product is multi-tenant, who is allowed to see what, and which parts of the workload belong in a background job. Gem choices get made here too, because every gem is something you will be upgrading for years.
Key Deliverables
- Domain & Schema Sketch
- Authorisation Model
- Gem & Service Choices
- Sprint Roadmap
Wireframes and prototypes worked through against the real data model, so a screen never implies a query the schema cannot answer cheaply. We design for Hotwire — partial updates rather than full page swaps — which keeps the frontend inside the Rails app instead of becoming a second codebase.
Key Deliverables
- Wireframes & Flows
- Interactive Prototype
- Component & Style System
- Responsive Layouts
Feature work in short sprints. Specs first for anything with logic in it, service objects where a model has genuinely outgrown itself rather than by reflex, and every pull request read by a second developer. N+1 queries get caught by a test that counts queries, not by a trace from production.
Key Deliverables
- Sprint Releases
- RSpec Suite in CI
- API Documentation
- Reviewed Pull Requests
Staging mirrors production closely enough to be worth trusting. Migrations are written so the old code and the new schema can both run during a rollout, Brakeman and a dependency audit run in CI, and the rollback is rehearsed before the release rather than improvised during it.
Key Deliverables
- System & Integration Tests
- Security Scan in CI
- Backward-Safe Migrations
- Rehearsed Rollback
After launch the work is queue depth, slow queries, error rates and version drift. We bump Ruby, Rails and gems while the diffs are small, and keep a running note of what would break at the next order of magnitude of traffic. Cover and response times are agreed per engagement.
Key Deliverables
- Error & Performance Monitoring
- Scheduled Version Upgrades
- Security Patches
- Feature Sprints
Industries We Serve
Where Rails Earns Its Keep
The framework is the same everywhere. What changes is the data model, the read-write balance, and what a bad day costs.
eCommerce & Retail
Catalogue, cart and order state, with the checkout path treated as the part that must not fail. Browsing is read-heavy and cached hard; writes stay in the database where they can be reasoned about.
Social Networking
Feeds, follows and messaging. The real decision is fan-out — write to every follower's timeline, or assemble it on read — with Action Cable for the parts that have to arrive without a refresh.
Publishing and News Sites
Publishing workflows under heavy read traffic and sharp spikes. Fragment caching and a CDN do most of the work, while the editorial side stays usable by people who are not engineers.
FinTech & Banking
Ledgers that have to balance, idempotent payment handlers, and an audit trail that records who changed what and when. Designed to support the controls your compliance team has to evidence; scope agreed per engagement.
Healthcare
Patient records, scheduling and messaging, with access rules enforced in the models rather than only in the interface. Designed to support the privacy obligations you operate under, with scope agreed per engagement.
SaaS Platforms
Multi-tenancy settled on day one — row-scoped, schema per tenant, or separate databases — because retrofitting it later is a rewrite. Then subscriptions, plan limits and the reporting your team asks for in month three.
Learning Platforms
Courses, cohorts, progress and assessment. Traffic arrives in spikes around deadlines, so grading, transcoding and report generation belong in the queue rather than the request.
Enterprise Systems
Internal tools, CRM-adjacent systems and admin platforms that stay in service for years. SSO, role-based access and integrations with whatever is already in the building, written so the next team can maintain it.
