We have been building software for over 15 years, more than 12 of them freelance. In that time we have supported companies and public authorities in planning, developing and operating demanding software projects — both within existing teams and as independently delivered solutions.
Our focus is on cloud-native services and running containers on Kubernetes — from concept and proof of concept through development into operation, including CI/CD, secret management, monitoring and test automation. As an iSAQB-certified software architect (CPSA-A) we bring structure and proven methods to design, architecture and documentation — most recently in the public sector and the automotive industry, throughout in agile teams (Scrum).

Fluxo — material & goods-flow control
A long-lived custom solution for a recycling operation with a complex separation process, run entirely in the Azure cloud: capturing production, warehouse and booking data, controlling the separation process and dashboards — solely responsible from concept to operation. The desktop client (WPF) is currently being migrated to a web interface.
Result: In production for over 10 years, with ongoing process optimisation.

European Social-Security Data Exchange (EESSI)
A large public-authority project connecting to a European data-exchange network: modernising existing components into Quarkus services on a Kubernetes cluster (Rancher), with an AS4 adapter including signature verification, Kafka messaging and GitOps operations.
Result: Traceable data migration and standards-compliant, signature-secured communication in production K8s operation.

Car-sharing platform
A greenfield platform for a mobility provider, in close collaboration with iOS and Android teams: serverless middleware orchestrating external services across a multi-cloud landscape (GCP, GKE, Azure B2C), designed event- and domain-driven.
Result: Scalable, maintainable middleware as the backbone of the app landscape.
- GCP
- Kubernetes (GKE)
- Azure B2C
- Terraform
- Serverless
- DDD
Telematics/fleet-management migration
Migrating existing telematics services from JEE/WebSphere into a new cloud environment: rebuilt as Spring Boot services on Kubernetes, defining the target architecture and automated deployments (Azure DevOps).
Result: A cloud-native target architecture instead of a WebSphere monolith, with automated deployments.
- Spring Boot
- Docker/Kubernetes
- Azure DevOps
- Azure ARM
- Pact
Identity & API services
Highly dynamic REST services around identity and user data: providing and validating generic JSON objects and secure sign-in via single sign-on (OAuth2/OpenID Connect, PingFederate).
Result: Flexible, secure API services with standardised authentication.
- Spring
- OAuth2/OIDC
- PingFederate
