Customised software development for companies

We develop software that grows with your goals: secure, compliant and maintainable in the long term. From architecture to operation.

Your business is unique. Your software should be too.

Do you want your IT to grow with your goals? We develop customised software solutions that fit into your IT landscape, simplify processes and significantly improve user experience. We pay attention to security, compliance and short release cycles so you can remain flexible.

Your systems should be reliable, expandable and easy to maintain, not just today but in the long term. To achieve this, we work in line with ITIL, Scrum and ISO 27001, with quality management in line with ISO 9001 and auditable delivery processes.

  • Digital sovereignty: you retain control over data, code, infrastructure and interfaces
  • Modular full-stack solutions that grow with your requirements
  • Collaboration remote, hybrid or on-site
  • Experienced and certified teams

Systematic software development: our service portfolio

As a partner for business-critical IT systems, we support you end-to-end. Our services can be flexibly combined for rapid results in complex, regulated environments.

  • Software architecture

    Modular, future-proof architectures integrate into your existing infrastructure. We take security requirements, integration needs and regulatory specifications into account right from the start. This creates stable systems with clear interfaces, excellent maintainability and reliable compliance.

  • Web and back-end development

    Based on proven technologies such as React, Angular and Vue as well as Java, Spring Boot and Kotlin, we develop web applications and powerful server components. The focus is on user-friendliness, performance and long-term maintainability.

  • Mobile applications

    Whether iOS, Android or cross-platform, our apps are user-friendly, integrated and secure. Integration into your system landscape ensures consistent data and uniform security standards. A well-thought-out UI/UX concept increases acceptance.

  • Interfaces and APIs

    Professional API development and tried-and-tested integration patterns create stable, traceable connections between all components. We support REST, GraphQL and SOAP as well as event-driven approaches with messaging and streaming.

  • Testing and quality assurance

    Automated testing, continuous integration and structured quality assurance deliver consistent results even with short release cycles. ISTQB-certified testing experts use modern testing methods and ensure verifiable quality.

  • DevOps, cloud and operations

    Continuous delivery, containerisation with Docker and Kubernetes and hosting in the cloud or on-premises ensure stable operations. We integrate applications into Azure, AWS or the Google Cloud Platform. Pipelines and infrastructure as code increase speed, reproducibility and audit readiness.

  • Agile and classic approaches

    Depending on the project, we work with Scrum, Kanban or tried-and-tested classic models. Interdisciplinary teams work closely with your departments. Our teams are certified in requirements engineering (CPRE), software architecture (CPSA), test management (ISTQB) and project management (Scrum, PRINCE2, PMP).

When is customised software worthwhile?

In complex corporate landscapes, standard software quickly reaches its limits. Process mapping is incomplete, legacy systems are difficult to integrate, and requirements such as the GDPR, the BaFin guidelines or DORA often require compromises. With custom software, you remain flexible and in control.

Our solutions are adapted to your processes, security and governance requirements. You retain full control over code, data, interfaces and release cycles. Thanks to automated tests, CI/CD and traceable processes, even weekly releases can be high in quality.

  • Business processes with special rules and exceptions that standard software cannot reliably map
  • Specialist applications with multiple role and rights concepts and high requirements for traceability
  • Data consistency and integration across many systems, both synchronous and asynchronous
  • Mobile solutions for field work with secure offline operation
  • Automation of workflows, approvals and rule-based decisions
  • Modernisation of existing systems through modular extensions, data migration and gradual replacement

Our technology stack

We rely on proven technologies. On top of that come focus areas such as AI-powered development and automation, video communication in digital applications and augmented reality for complex visualisation.

  • Languages

    Java, Kotlin, C/C++, Swift, Python and JavaScript.

  • Frameworks

    Spring, Java EE, Ktor, Node.js, Quarkus, Apache Wicket, Kotlin Multiplatform and FastAPI.

  • Frontend

    HTML/CSS, Angular, Vue, React and React Native, SwiftUI, Jetpack Compose and Figma.

  • Deployment

    Azure, AWS, Docker, Kubernetes, GitLab CI and VMware.

  • Databases

    SQL with Oracle and PostgreSQL, NoSQL with MongoDB, Cassandra and Elasticsearch.

  • Application servers

    Tomcat, Apache, JBoss and NGINX.

How do we use generative AI?

We use generative AI where it offers real added value: to accelerate analysis, prototyping, test case generation or documentation. The architecture and approach set clear boundaries. The goal is quantifiable benefit, not use for its own sake.

Whether generated or written manually, every piece of code goes through the same audit trails. The four-eyes principle, code reviews, automated testing, analyses and reproducible builds are firmly anchored in how we work. In this way, results remain reliable, auditable and trustworthy over the long term.

Your data remains under your control. We use European storage locations, encrypted connections and clear access concepts. If desired, we operate models exclusively in your cloud or on-premises and follow your requirements regarding logging, rights management and data minimisation.

Using GenAI with purpose instead of producing legacy issues

We use GenAI intelligently and purposefully to create real added value. After all, more code usually just means more legacy issues.
