Software development

Compliance-proof customised software development

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 integrate seamlessly 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 at all times. Our goal is to ensure that your systems are reliable, expandable, and easy to maintain, now and in the long term. Together we will create the basis for your sustainable digital success.

We see ourselves as a partner who takes your requirements seriously and focuses on your individual strengths. For us, successful software development means creating solutions that truly advance your organisation and keep you operational into the future.

Systematic software development: our service portfolio

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

Modular, future-proof architectures integrate seamlessly into your existing infrastructure. Security requirements, integration needs and regulatory specifications are taken into account right from the start, creating robust systems with clear interfaces, excellent maintainability and reliable compliance.

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

Whether iOS, Android or cross-platform, our mobile applications are user-friendly, integrated and secure, supporting your processes exactly where it’s needed. Integration into your system landscape ensures consistent data processing and uniform security standards. A well-thought-out UI/UX concept increases acceptance.

Interfaces enable smooth, traceable data exchange within your system landscape. Professional API development and tried-and-tested integration patterns create stable connections between all components. We support REST, GraphQL, and SOAP, as well as event-driven approaches with messaging and streaming.

Automated testing, continuous integration and structured quality assurance deliver consistent results even in the event of complex requirements and short release cycles. ISTQB-certified testing experts use modern software testing methods and ensure verifiable quality.

Continuous delivery, containerisation with Docker and Kubernetes, and flexible hosting models in the cloud or on-premises enable stable operations that fit your IT strategy. Applications can be perfectly integrated into Azure, AWS or the Google Cloud Platform. Automated pipelines and infrastructure as code increase speed, reproducibility and audit readiness too.

Depending on the project requirements, agile methods, such as Scrum or Kanban, and tried-and-tested classic models are used. Interdisciplinary teams work closely with your departments and ensure a successful project through transparent communication and continuous feedback. To begin with, we will work together to develop a sustainable architecture that takes into account business requirements, regulatory frameworks and existing IT structures.

How you can benefit

Digital sovereignty and full stack

We develop software from A to Z, while you retain control over data, code, infrastructure and interfaces. Our modular full-stack solutions grow with your requirements and can be expanded at any time.

Security and quality standards

Security and quality are firmly anchored in our projects. We work with processes that are compliant with ITIL, Scrum and ISO 27001, quality management in line with ISO 9001, and auditable delivery processes.

Flexible collaboration

You will benefit from flexible collaboration – remote, hybrid or on-site. Our teams take the burden off your resources and deliver customised solutions, allowing you to focus on your core business while we take care of the technology.

Experienced and certified teams

Our teams have many years of experience and certifications in the areas of requirements engineering (CPRE), software architecture (CPSA), test management (ISTQB) and project management (Scrum, PRINCE2 and PMP).

Usage scenarios for individual software solutions

  • Business processes with special rules and exceptions that standard software cannot reliably map
  • Complex specialist applications with multiple role and rights concepts as well as high requirements for traceability and auditability
  • High demands on data consistency and system integration across many systems, both synchronous and asynchronous
  • Mobile solutions for field work and work independent of location, with secure offline operation and connection to identity and device management
  • Automation of technical and operational processes, such as workflows, approvals and rule-based decisions
  • Modernisation of existing systems through modular extensions, new interfaces, data migration and gradual replacement

Added value of customised software development

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

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

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 so that GenAI remains seamlessly integrated into your processes, always with the goal of achieving quantifiable benefits and not used for its own sake.

Whether generated or written manually, every 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, we ensure that results are robust, auditable and trustworthy over the long term.

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

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

How does collaborating with us work?

Working with us is flexible – it can be remote, hybrid or on-site. We tailor the setup to suit your organisation. All work is carried out according to ITIL, Scrum and ISO 27001. This ensures stable workflows, clear roles and maximum connectivity to your processes.

The starting point of every project is to gain a precise understanding of your goals, processes and general conditions. CPRE-certified specialists analyse your requirements according to the standards of the International Requirements Engineering Board (IREB) and develop concrete, prioritised requirements from this.

Business analysis & requirements engineering

Based on the requirements, a robust system design is created that takes your technical and regulatory specifications into account. CPSA-certified software architects develop an architecture according to ISO 25010, taking into account all aspects such as usability, performance efficiency, security and maintainability.

Architecture and technology design

In interdisciplinary teams, development takes place in short cycles with regular coordination. Functional interim results make progress visible early on and enable active feedback. Depending on the project requirements, agile methods, such as Scrum or Kanban, and classic models are available.

Agile development and iterative rollout

Even after the go-live, we will continue to support you as a partner with regular testing, smooth operation and targeted continuous development in line with your strategic goals. Services are based on ITIL-compliant processes and include structured incident management, event handling and service level agreements.
