Development

NexGen develops custom software for organisations, with a particular focus on security, maintainability and controllable architectures.

Software you can control.

Custom software makes sense when standard products do not cover the requirements or when data must not leave the organisation. What matters is that the solution can be maintained, understood and operated securely for years.

We prefer established, long-term supported technologies such as Java and Jakarta EE, clear architectures and a small number of dependencies. This reduces attack surface and maintenance effort.

Focus areas

Java / Jakarta EE
Long-lived enterprise applications on an open, standardised technology stack.
Web Applications
Web applications with a clean separation of presentation and logic, accessible and without unnecessary dependencies.
Backend systems
Business logic, data storage and process automation with clear responsibilities.
APIs
Documented, versioned interfaces with authentication and input validation.
Enterprise integration
Connecting existing systems – controlled, logged and fault-tolerant.
On-premises solutions
Software for operation in your own infrastructure, without dependency on external cloud services.
Security tools
Tools that automate security processes in your organisation and make them traceable.
Custom business software
Solutions for processes no standard product fits.

Approach

  1. Clarify requirements

    Business goals, constraints, protection needs and operating environment are defined together.

  2. Architecture and security concept

    Components, data flows and trust boundaries are designed and documented.

  3. Develop iteratively

    Short cycles with working increments, code reviews and automated tests.

  4. Hand-over and operation

    Deployment, operations documentation and, on request, maintenance and further development.

What you get

  • Source code and documentation, traceable and ready for hand-over
  • Reasoned architecture decisions
  • Automated tests and reproducible builds
  • On request, a software bill of materials (SBOM)

Let us talk about your software project.

Whether it is a secure development process, an ISMS, preparing for the Cyber Resilience Act or controlled use of AI: a first conversation clarifies where you stand and which next step makes sense.
