Mobile App Development Review from Artur Ozierański
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.
