CUSTOM RUBY SERVICES
Advanced Rails Engineering
We build applications optimized for developer happiness and extreme scale. From executing seamless legacy Rails upgrades to replacing massive React SPAs with blazing-fast Hotwire architectures.

We scale the 'Majestic Monolith'. We utilize component-based architectures (engines and namespaces) to keep massive Rails codebases strictly organized, avoiding the unnecessary network overhead of premature microservices.
We unlock massive speed gains. We upgrade applications to Ruby 3.x, heavily utilizing the new YJIT (Yet Another Just-In-Time) compiler and Ractors to achieve highly concurrent, C-level execution speeds.
We eliminate complex JavaScript build steps. We utilize Rails 7+ Hotwire, Turbo, and Stimulus to deliver Single Page Application (SPA) speeds using pure HTML over WebSockets, drastically reducing frontend complexity.
We keep your web requests blistering fast. We architect robust, distributed background job queues utilizing Sidekiq and Redis to handle heavy PDF generation, email blasts, and massive database imports asynchronously.
We eliminate database bottlenecks. Our DBAs rigorous profile your Rails logs to destroy N+1 queries, implement advanced counter caches, and utilize `bullet` to ensure Active Record never cripples PostgreSQL.
We build headless backends. For native mobile apps or separate React frontends, we architect blazing-fast Rails API-only servers, utilizing GraphQL Ruby or FastJSONAPI to drastically reduce payload sizes.
We modernize aging infrastructure safely. We execute methodical, test-driven upgrades from legacy Rails 4/5 directly to modern Rails 7/8, ensuring zero downtime and patching critical CVE security vulnerabilities.
We refuse to deploy broken code. We enforce rigorous Test-Driven Development (TDD) utilizing RSpec and FactoryBot, writing impenetrable model, request, and system specs to guarantee business logic integrity.

Ruby FAQ
What tech leaders ask about Ruby before pulling us in:
Absolutely not. Rails remains the fastest way to build a web application on the planet. Massive companies like GitHub, Shopify, Airbnb, and Stripe are built on Ruby on Rails. With the massive performance boosts in Ruby 3 (YJIT) and the frontend revolution of Hotwire in Rails 7, the framework is experiencing a massive renaissance among enterprise startups.
Historically, teams built a Rails API and a completely separate React frontend (a Single Page App). This required two codebases, two engineering teams, and complex Webpack builds. Hotwire (HTML Over The Wire) allows us to send tiny snippets of HTML directly to the browser over WebSockets. This provides the exact same instant, page-refresh-free experience as React, but with a fraction of the code.
Ruby 3 introduced YJIT (Yet Another Just-In-Time Compiler), built by Shopify. Instead of interpreting code line-by-line, YJIT compiles heavily used Ruby code into native machine code while the app is running. This results in massive, free performance boosts (often 20-30% faster response times) without changing a single line of business logic.
For 95% of companies, we strongly recommend the 'Majestic Monolith'. Microservices introduce massive network latency, complex distributed tracing, and difficult deployments. Instead, we build 'Modular Monoliths' using Rails Engines, which keeps your codebase strictly organized into separate namespaces while maintaining the simplicity of a single deployment pipeline.
The most common issue in Rails is the 'N+1 query' problem, where rendering a list of 50 users causes 50 separate database calls to fetch their avatars. We rigorously utilize tools like the `bullet` gem to detect these issues in development, fixing them by using `.includes()` to eager-load associations in a single, highly optimized SQL query.
We utilize Sidekiq, the industry standard for background processing in Ruby. If an application needs to generate a massive PDF or send 10,000 emails, doing that during a web request will cause the server to time out. Instead, we push a job to a Redis queue instantly, and a separate fleet of Sidekiq worker processes executes the heavy lifting in the background.
Yes, but it must be done methodically. Skipping major Rails versions (like jumping from 4 to 7) will break the app. We execute 'dual boot' upgrades, writing comprehensive RSpec test suites first to guarantee business logic, and then upgrading the framework one version at a time to ensure zero production downtime.
We heavily utilize RSpec. RSpec is a behavior-driven development (BDD) testing framework that is incredibly expressive. We use it in conjunction with FactoryBot (to generate complex test data) and Capybara (to simulate exact user clicks in a headless browser), ensuring that every edge case is covered before code reaches production.
