Here's how we can help you.
Web application design and development
We build bespoke web applications based on Ruby. We provide full technology stack: Rails back-end, front-end (React, Vue.js or other tailored to the project), databases (PostgreSQL, MySQL, etc.) and cloud hosting. We create scalable architectures, prepared for the growing number of users and new functionalities.
Development and maintenance of existing Ruby applications
We take over the care of already running projects written in Ruby. If you're short on manpower or your current application needs improvement, our experts will examine the code, suggest improvements and start delivering value quickly. We upgrade applications to the latest versions of Rails, improve performance, scale infrastructure and provide ongoing support and maintenance. With us, your application will be secure, fast and ready for future challenges.
Optimization and modernization of legacy code
Do you have an older application in Ruby on Rails that is causing problems? We specialize in rescue projects: we optimize obsolete code, clean up the architecture, remove performance bottlenecks. We understand the challenges of older versions of Rails and can breathe new life into key systems, minimizing the risk of downtime. Our goal is to extend the life of your system and reduce maintenance costs through improvements.
Integrations and APIs
We enable seamless communication of your application with other systems. We create APIs (RESTful, GraphQL) in Rails and integrate with external services (e.g. payment systems, SaaS platforms, mobile apps). Your application can become the heart of an ecosystem of different tools - we'll make sure all the pieces work together seamlessly.
Outsourcing of specialists / dedicated Ruby teams
Need to strengthen your development team? We offer you the opportunity to hire experienced Ruby on Rails developers on a short-term or long-term basis. Our developers can join your project, supporting it with their skills, or we will create a whole dedicated team (developers, testers, DevOps) working exclusively for you. You choose the collaboration model - we provide proven people who will quickly find their way into your work environment, communicating fluently in English and adapting to your processes. It's a flexible way to increase capacity without recruiting on your own.
"I have come to know Dariusz and his team as excellent business partners. I have absolute trust in my business partner in terms of general conditions, reliability and quality of work."

USEO BENEFITS
Why choose USEO for
Ruby on Rails projects?
Why choose USEO for
Ruby on Rails projects?
Experience and expertise
Ruby on Rails is our daily bread. We have been implementing projects in Rails even before it became mainstream - our seniors remember older versions of Rails from 10 years ago, and today they efficiently use the novelties of Rails 8. Thanks to this, we can advise you on the best practices and avoid the pitfalls that are easy to fall into without relevant experience. Your project will end up in the hands of people who know Rails inside out.
Full commitment to customer success
We treat every project as if it were our own. Before we start coding, we dig into your business to understand your goals and challenges. We propose solutions that will realistically improve your processes or differentiate your product in the market. We work agile (Agile/Scrum) so you have full control over progress and the ability to make changes on the fly. Our proactive approach means that we often suggest ideas for improvements or new features to clients, instead of just “ticking off” tasks.
Code quality and reliability
We use best engineering practices to make your project solid from the ground up. Every line of code goes through code review, we have an extensive set of automated tests (Rails makes testing easy, which we take full advantage of), and we implement deployments in the CI/CD model - so new versions of the application appear quickly and without errors. We know how important reliability is: the applications we develop achieve high availability (uptime), and we catch any errors before they reach end users.
Flexibility of the cooperation model
We can adapt to your needs - we can take over the entire end-to-end project or work closely with your internal IT department. If you have a sudden deadline, we can quickly augment the team working on the project to meet deadlines. If the project comes to an end, we can stay on standby with minimal staff to respond to current needs and develop the application iteratively. This flexibility means you optimize costs - using our resources exactly when you need them.
Trust and references
Testimony to our effectiveness are the successes of our clients. We successfully built a 13-year partnership with a company from Switzerland developing an HR portal - from prototype to market-leading platform. We helped an Australian startup solidify a global remote work platform by developing its core in Ruby. Relationships like this pay off with domain knowledge and trust that can't be bought - when choosing us, you are choosing a partner with a proven track record of success. Our maximum ratings from clients (★★★★★ on Clutch) translate into peace of mind for you - you know your project is in good hands.
More case studies and references are available upon request or in the case study section.
