Backend Development

Backends form the invisible foundation of your products in the digital world.
With the development of custom backends, we create added value for your connected products
and lay the groundwork for data-driven decisions in your business.


Maximizing Added Value -
enabled by Custom Backend Solutions

Unlocking new business opportunities through data from connected products is at the core of our focus.
The greatest added value of a connected product comes when the emerging IoT data is intelligently utilized to enable automation. This encompasses not only automatic control but also triggering notifications as part of continuous device monitoring. Each device type and use case has unique requirements. Consequently, you require a robust and secure solution for data and command reception, storage, processing and analysis, as well as data and command forwarding.
Our strength in collaborative projects lies in conceptualizing the right approach, even in the face of specific challenges.
If you aim to generate added value through the utilization of data from connected products,
we are your experienced development partner to maximize the benefits through a custom backend.

Customized Backend - Enhancing Your Flexibility and Independence

When it comes to realizing your specific requirements and ensuring your flexibility,
we focus on developing individual system architectures and backends. The use of IoT products often demands short response times or even real-time interactions. Additionally, there are frequently specific requirements for analyzing and leveraging the generated data, necessitating the development and integration of tailored solutions.
To ensure swift and robust implementation, we leverage existing components in the development process. Specifically, we combine our own established solution components with those of renowned hyperscalers.
In summary, a backend developed by us provides you with independence from third-party products and the necessary flexibility to fully realize your specific use case.

Versatile Backend - For Your Data-Driven Future

An individualized backend is pivotal for the intelligent interplay between data processing and user interaction. With our foresight, particularly in architecture selection, we lay the foundation for harnessing your data's potential. The backend assumes key functions such as device management, FOTA updates, and the creation of digital twins for your physical devices. Moreover, it acts as an interface to other systems like apps and ensures secure data transmission. Providing pre-processed data and data management are additional core tasks of the backend. It also enables seamless integration of new features, such as data science analyses based on your IoT data. We understand that it's not just about securely storing data but also making it readily usable to generate added value.
This empowers you to make informed business decisions and stay future-ready.
