Web System and Smartphone Applications Development

We use a unique method called MVP (Minimum Viable Product). By developing an MVP, our clients can see and test the product based simply on their general concept with not much details to worry about. It’s a good way to do a ‘reality check’ for our clients if the product is feasible. We then scrape the modifications and additions using an Agile project management approach, and let our clients ‘road-test’ the prototype before final development and completion. By visualizing and taking everything into consideration, we can reduce the time spent defining requirements and be able to move swiftly to specific improvements for each stage to achieve a realistic product launch schedule. 

Using React Native, we are able to develop multi-platform applications for any type of device or operating system. Our expertise in JavaScript framework enables us to build any type of application for iOS and Android, as well as for web browser.
