Ruby on Rails development and support
Leoio is a team of Ruby developers. We build Ruby on Rails web applications from scratch, take over and support live projects, upgrade outdated Ruby and Rails versions, and build AI features into products. You talk directly to the engineers who write the code.
Services
Ruby on Rails development
Web services, customer portals, marketplaces, CRMs and SaaS products. We ship an MVP in a few weeks and keep building from there.
Support and maintenance
We fix bugs, keep the app stable and secure, update gems and ship improvements on a monthly plan.
Legacy project support
We take on old projects with no docs, no tests and no original developers. We learn the codebase, stabilize it, add test coverage and refactor gradually while the site keeps running.
Ruby and Rails upgrades
We move projects from old versions to Rails 8 step by step, with tests at every stage and no downtime.
Audits and performance
We find slow database queries, memory leaks and vulnerabilities, then speed up pages and Sidekiq background jobs.
APIs and integrations
REST and GraphQL APIs for mobile apps, plus integrations with payment providers, CRMs, ERPs and other third-party services.
Stack migration
We move projects from PHP, Python or Node.js to Ruby on Rails and replace outdated parts of the stack: frontend, database, hosting. The move happens in stages, with no downtime and no data loss.
Redesign
We refresh the look and usability of live sites: a new interface, responsive layouts for phones and faster loading. Page URLs stay the same, so you keep your search rankings.
AI transformation
We add AI to live products: chat assistants and search over your data, automatic processing of documents and requests, content generation and classification. We connect models through APIs and build them into your Rails app without rewriting the project.
DevOps and hosting
We set up servers, Docker, Kubernetes (k8s), Kamal, CI/CD, monitoring and backups.
Technologies
Ruby, Ruby on Rails, Hotwire (Turbo and Stimulus), PostgreSQL, Redis, Sidekiq, RSpec, Docker, Kubernetes, Kamal

FAQ
How much does Ruby on Rails development cost?
It depends on the features and integrations you need. After a short call we send an estimate broken into milestones, each with a timeline and a fixed price.
Do you take over projects built by another team?
Yes. We start with an audit of the code, tests and infrastructure, walk you through the risks, and only then take the project on.
Can you upgrade an old project to Rails 8?
Yes. We upgrade step by step through each major Rails and Ruby version, running the tests at every stage so the site keeps working with no downtime.
Why Ruby on Rails rather than another framework?
Rails lets you launch quickly and keep growing the product with ease: databases, background jobs, email, file uploads and security are built in. GitHub, Shopify and Basecamp run on it.
What does Rails support include?
Bug fixes, security and dependency updates, monitoring, backups, small improvements and advice. We agree on the scope in a monthly plan.
