Ruby on Rails has built more startups than almost any other framework. GitHub, Shopify, Airbnb, Basecamp: All started on Rails. The reason is simple. Rails let small teams ship working products fast, with clean conventions and battle-tested patterns. But to get the most out of it, you need engineers who know the framework inside out. That’s where ACME ONE comes in.

Ship working products in weeks, not months, using Rails conventions, Hotwire, and Stimulus for fast iteration.
Build multi-tenant SaaS apps with secure authentication, billing integrations, and scalable backend architecture.
Design clean JSON APIs and GraphQL endpoints to power web apps, mobile apps, and third-party integrations.
Upgrade Outdated Rails versions, refactor monoliths, and migrate to current Ruby and Rails releases without breaking production.
Tune for slow queries, add caching with Redis, and optimize background jobs with Sidekiq for high-traffic applications.
Write unit and integration tests with RSpec and Capybara, then deploy reliably through Docker, AWS, Heroku, and CI/CD pipelines.
