We are a trusted IT software company that started 6 years ago. We create ERP, CRM systems, FinTech, eHealthcare and other business automation solutions in the form of Web and Mobile Apps. Also, we've developed our own product - OMS (Online Marketplace Software). OMS is the easiest as well as a cost-effective way to launch a custom online marketplace within one week. Our services include Business Analysis, Backend/Frontend development, QA, UX/UI design. We prefer to work on a time and materials basis, with the help of SCRUM methodology. T&M model means the project moves in 2 week long cycles, giving the client fewer investments for detailed tasks specifications. Also, it helps us to be more flexible if there is a need to change priorities about features or add new functions.
