We utilize MACH architecture - for more flexibility, scalability and speed

We base our projects on MACH architecture – a modern technological framework consisting of four key components: Microservices, API-first, Cloud-native and Headless.

MACH Architecture allows you to rapidly adapt and integrate the latest technologies without being tied to specific vendors or technology stacks. It also supports a more personalized customer experience and enables faster updates and improvements, driving innovation and maintaining competitive advantage.

  • What is the difference between custom software development and off-the-shelf software?

    Mehr lesen

    Custom software development refers to the development of software solutions that are specifically tailored to the needs of a company. Off-the-shelf software refers to existing software products that are generally available and can be used by many companies.

  • How much does custom software development cost?

    Mehr lesen

    The cost of custom software development depends on various factors, such as the scope of requirements, the complexity of the project, the technologies used and the amount of work. Therefore, the costs can vary greatly and must be calculated individually. It is advisable to obtain a quote from an experienced provider who can give an accurate estimate of the costs based on the specific requirements.

  • How is it ensured that the developed software meets the requirements and needs of the company?

    Mehr lesen

    To ensure that the developed software meets the needs of the company, we rely on automated quality checks. These include automated tests, code reviews and manual checks by our developers. Through this process, we ensure that the developed software meets the expectations and requirements of the company and is ready for deployment.
