JetRuby provided staff augmentation services for us. developed a mobile app for a design platform. The team was responsible for implementing the backend server and admin panel, and frontend code. The team was made up of experienced developers that have great communication skills, which made resolving any issues or questions a breeze. JetRuby developers kept up-to-date with the latest technologies and trends in development and suggested updates and improvements to the application as needed.
Web Design Review from Patrice Archer
They developed a SaaS web platform with smart scheduling and automation tools for us at and built the platform's front- and backend and integrated a custom analytics dashboard and calendar integrations. But to be honest what impressed us most was how deeply they engaged with our vision. They didn't just write code they challenged assumptions, proposed better workflows, and contributed as if they were part of our internal product team. Their ability to think strategically and focus on user experience made them feel more like tech partners than a typical outsourced vendor.

We hired Altoros engineers as an essential extension of our client-facing internal teams. This was a tough decision because our reputation as a brand depends on the overall efficiency of our processes and we needed to make sure all risks are mitigated when it comes to delivery. Altoros has not let us down.Together with Altorosians we successfully deployed a number of tough and technologically complex projects on time. So our collaboration is certainly set to continue.
Software Development Review from Victoria Lewis
We enjoy working with our team, Roman Yurkin, Tatyana Kobzar, Svetlana Kalchanka and Tatiana Anop. They bring expertise and immense value to our business with each piece of work they complete. They are a major part of our business development and delivery.
Ruby on Rails Review from Greg Lipper
In my 30 years in the software business, I have never had as positive an experience with an outsourced development services provider as I have with Altoros. Each Altoros engineer we have worked with has been strong technically, estimated development times accurately, completed projects on time, and delivered code and projects with high quality. Beyond that, they have helped improve our thinking and approach with suggestions and ideas that were better than the spec of instructions we supplied.
