Ruby and Ruby On Rails

Ruby is our main domain, so we build efficient and scalable digital products. We provide a full range of work: from UX/UI design as well as backend and frontend — from implementation to maintenance. We use the latest technologies (Rails 6/7/8, React, AWS, and more) to deliver a solution perfectly tailored to your business.
And if you have an older application in Ruby that is causing problems or no one wants to take on the upgrade, we specialize in rescue projects: we optimize obsolete code, clean up architecture, remove bottlenecks, improve application performance. We perfectly understand the challenges of older versions of Rails and can breathe new life into key systems, minimizing the risk of downtime.
