Our process


Analysis & Consultation

At the beginning of the process, we conduct an analysis in which we work closely with clients to understand their unique needs, allowing us to create a precisely targeted software solution brief.

Project specification

The analysis results in clear requirements that are understood and agreed by both parties, so that we set the right course from the start.

Design & Prototyping

The next step is the design of the application and prototyping of the navigation and user interface, which allows it to be fine-tuned before the start of development and gives the customer an initial idea of the form of the emerging application.

Development & Testing

We develop iteratively, which allows for client involvement in the development thanks to their continuous feedback. This method increases the flexibility of development and accelerates the achievement of an optimal solution, responding to customer needs in real time.

Minimum Viable Product (MVP)

Once the minimum functional prototype is ready, we present it to the customer and start collecting suggestions. In this way, our client monitors the application continuously and controls the desired direction of development.

Acceptance testing and handover

After the product development is completed, acceptance testing is performed by the client, who finally verifies everything and incorporates any comments. The product is then formally handed over to the customer.

Operation & Support

Wherever the client wishes, we offer traffic management and follow-up support. We are happy to develop the products further with additional functionalities.

Our expertise

With our company, you will gain access to a wide range of expertise and skills. We specialize in Microsoft’s robust development ecosystem, which means developing in C# using .NET and Azure tools and their cloud-native services. Our team will ensure you both select the optimal solution, whether in the cloud, on-premise or on endpoint devices, and deploy and manage it. For web applications, we leverage the JavaScript ecosystem and the React library for frontend development and ASP.NET for the backend part of the solution. For mobile apps, we use Xamarin.Forms or React Native, so we can develop your complete job without a lot of unnecessarily complex solutions and an excessive amount of disparate technologies. The simplicity of our solutions is their strength.
