Back to original languageAbout Stephan
I help companies implement their .NET projects faster, more stably, and more scalably – with clean architecture, high code quality, and a reliably running Azure infrastructure.
If you are looking for someone who solves problems instead of managing them, you are in the right place.
For over 20 years, I have been developing .NET solutions in demanding industries such as banking, payment, logistics, automotive, public transport, gastronomy, payroll & HR, and broadcasting. This experience allows me to quickly understand complex requirements and translate them into robust, maintainable systems that deliver real business value.
I take on not only the architecture and development but also the complete Azure operations – including CI/CD pipelines in Azure DevOps, automated deployment, monitoring, security concepts, and clean secrets management.
The result: fewer outages, faster releases, more stable systems.
Services that deliver results
- Development of high-performance .NET backends, APIs, and integration solutions
- Modernization, refactoring, and architecture consulting
- Setup and operation of Azure infrastructures (App Services, Functions, Key Vault, Storage, Networking)
- Creation and optimization of CI/CD pipelines
- Interface development (REST, SOAP, Messaging, Event-Driven)
Why customers work with me
- Quick familiarization with complex domains
- Focus on stability, maintainability, and scalability
- Experience in regulated, security-critical areas
- Clear communication, reliable execution, pragmatic solutions
