Project status amber?

We are a team of 25 experienced engineers in Düsseldorf and at our subsidiary in Prague. We build enterprise software for corporations and mid-sized companies, run it ourselves and step in when things are on fire.

The deadline is slipping and the status report has been amber for weeks.
We find the actual root cause and get our hands dirty until it is green again.

Services

What we build. And run.

We rarely start from a blank slate. Our software fits into existing system landscapes and stays up to date there.

All services
  1. Custom software for complex processes

    Ordering platforms and business applications that sales, back office and partners work with every day. Instead of bending standard software, we build what your process actually needs.

    Java 21/25 · Spring Boot 4 · Vaadin 25 · React · TypeScript

  2. UI/UX without a training manual

    Together with specialised design partners we create Figma designs and clickable prototypes before a feature is commissioned. Our developers implement them directly.

    Figma · Clickable prototypes · Design systems · Storybook

  3. Workflow automation and integration

    Five systems, three departments, one signature: we model such processes in BPMN and connect what is already there. Every job either completes, goes into retry or surfaces as an incident. No order gets lost.

    CIB seven / Camunda 7 · OpenAPI · DocuSign · Microsoft 365

  4. Product modelling and rule engines

    Making complex products with many dependencies orderable online: we model rules, price corridors and approvals so they are checked live during configuration and tested like software.

    Rule engines · Price corridors · Regression tests · Versioning

  5. Cloud and infrastructure as code

    Reproducible environments on AWS or in your own data centre. We move grown setups into code step by step, without interrupting operations.

    AWS · Kubernetes · Proxmox · CDK for Terraform · OpenTofu

  6. Operations, monitoring and testing

    Pipelines with real end-to-end tests, monitoring that reports problems before your customers do, and an on-call team that knows the system from the inside.

    OpenTelemetry · Grafana · GitLab CI · Playwright · Chromatic

You build it, you run it.
since 2000

Hundreds of projects, mainly in telecommunications and fibre roll-out.

14 days

Release cycle with finished, working features instead of interim states.

1 contact

No sales layer, no cascade of project managers: you talk directly to the developers.

Project rescue

Engineers, not slide pushers.

When things are on fire, we go as deep as necessary. In the end, the root cause is found in the code or in a packet dump, not in a presentation.

  1. Understand the situation: code, architecture, operations
  2. Find the cause, not the symptoms
  3. Get our hands dirty until it is green
