Business Conduct

To Drive & Accelerate Software Development Innovation

The above sentence describes our mission as a software consultancy team. But, it wouldn’t be possible without great experts we have on board and their drive for doing great things. Our team is our greatest advantage over the competitors. We started as a really small group of friends but, over the years, our team has been growing dynamically. And, to maintain the great team spirit we share, we need to keep our standards in place.

Our values

We don’t follow best practices. We set them!

To stay in line with our vision that describes us as the leaders in React Native and cross-platform development and fulfill our mission “To drive and accelerate software development innovation” and to create a peaceful, diverse and open working environment, we worked out a set of our core values. 

We are seeking constant improvements, always ready to discuss, challenge and brainstorm ideas.

We are challenging existing solutions, the reality.

We are helpful, part of the React Native community, contributing, being a part of a larger group.

We create equal opportunities and make things easily accessible. All of our actions make the open source community more diverse.

We are top notch experts in what we do, and we are constantly striving for highest excellence when it comes to React & React Native development. 


Open Source leaders
