Software Architecture & Engineering
Benefit from flexible applications, short release cycles and stable systems – thanks to a Software Architecture that is designed for growth, efficiency and integration.
With modern Software Architecture, you can eliminate technical bottlenecks – in a structured, modular and scalable way.
Monolithic applications, rigid structures and code that is difficult to maintain are slowing down innovation and growth. At the same time, requirements are increasing: Faster releases, greater integration capability and platform resilience are essential today.
Software Architecture & Engineering creates the structural basis for high-performance systems. Instead of monolithic structures, modular architectures combined with domain-driven design enable the targeted further development of individual functions. For example, the customer portal can be updated independently of backend systems, eliminating release dependencies.
Technology that structures – for scalable, modular application architectures.

Structured applications, flexible further development and stable IT architectures.
How we support you.
We support you in developing modern software architecture, from analysing existing systems to implementing modular, structured applications. Whether monolithic legacy systems or fragmented services: Together we develop a scalable architecture for sustainable further development.
Our experts design software structures in line with your business logic, using domain-driven design, API-first approaches and standardised components. This results in integration-capable platform models that reduce technological complexity and ensure efficient long-term operation.
We analyse your existing software architecture in terms of modularity, coupling, expandability and technological risks. We analyse services, interfaces, data flows and code quality with a view to scalability, performance and operational stability.
The goal is a clear architectural target image that reduces technical debt, accelerates development and maps future requirements, providing a sound foundation for platform strategy and implementation.
We support the decomposition of monolithic systems into clearly delineated, technically motivated modules. With domain-driven design, we structure applications along their functional domains – e.g. order, customer or delivery – and clearly separate technical responsibilities according to bounded contexts. This improves testability, reduces sources of error and accelerates changes during operation.
With an API-first approach, we design your software architecture for integration right from the start, regardless of technologies, services or data sources. We define clear interfaces, standard formats and governance structures for internal and external communication.
In this way, we enable simple connection, improved interoperability and a structured expansion of your API ecosystem, forming the basis for automated processes and platform growth.
We support you in the selection, consolidation and strategic alignment of your technologies and platform components. Whether Java, .NET, Node.js, SAP or legacy – we evaluate technological fit, runtime environments, deployment options and depth of integration.
Together, we create a standardised software architecture that reduces technical diversity, lowers operating costs and enables future-proof scaling – locally, hybrid or in the cloud.
We identify technical debt in code, architecture and infrastructure and define realistic steps for targeted refactoring. In doing so, we prioritise risks and expenses, optimise structures and improve the basis for modern development methods.
In this way, you increase the release capability of your platform, avoid sources of error and ensure long-term maintainability, all without interrupting operations and with a clear architectural vision.
If you also want to renew or migrate existing systems technologically, we recommend our application modernisation services.
Your IT Transformation starts here.
Let’s talk about your goals.
Growing requirements, technological diversity and fragmented systems require a well thought-out architecture. With Software Architecture & Engineering, you can create modular structures, clear interfaces and a stable basis for scalable platforms. Domain-driven design, API-first and strategic modularisation ensure that your applications remain expandable and capable of integration in the long term.

FAQ
Do you have questions about Software Architecture & Engineering?
In our FAQ you will find concise answers to key topics relating to modular architectures, API strategies and scalable application systems.
Still have questions?
Scalability, integration capability and efficiency depend directly on the architecture. Digital platforms can only be developed further in the long term if systems are structured. A modern software architecture creates the basis for modular applications, stable data flows and technical resilience — all of which are indispensable for any sustainable IT strategy.
A modular architecture makes it possible to develop, test and provide individual components of an application independently of each other. This saves time, reduces complexity and improves maintainability.
A practical example: together with Accenture, we have developed a global cloud platform for Amadeus. Thanks to its modular structure, functions can be expanded in a targeted manner – for new travel services or seasonal peak loads, for example – without having to adapt existing systems.
An architecture assessment is particularly worthwhile in the event of increasing complexity, decreasing development speed or imminent system expansion. A review also provides valuable insights for the strategic further development of your IT landscape in the event of security gaps, a lack of testability or a high level of dependency on legacy systems.
Software architecture is always crucial when systems are complex, distributed or difficult to maintain. Typical use cases include platform projects with many modules, migrations of legacy systems, the introduction of microservices or API ecosystems and the development of scalable SaaS solutions. A clear architectural structure also provides the necessary technical stability when merging IT systems after company takeovers (post-merger integration) or when the feature scope is growing.
Our experts analyse existing structures, identify technical debts and define a clear target picture together with you. On this basis, we implement modular architectures with domain-driven design, API-first and clear service separation – open to technology, standardised and designed for sustainable expandability.
