Marcel Simmendinger

I am a software developer with over ten years of experience, starting as a system integration IT specialist, and today a lead developer with team responsibility.

What distinguishes me from pure developers: I understand both sides. Infrastructure and software. Linux, Docker, Kubernetes, Azure, I build the environment in which the software runs. And I build the software itself. C#, Python, React Native, AI integration. Those who can do both solve problems with the right tool, not with the one they currently know.

I decide pragmatically: in-house development when it makes sense, existing solutions when they fit better. No dogma, no over-engineering.

In my daily work, I have built and operated Kubernetes clusters, set up Azure DevOps pipelines with Kustomize, developed AI assistants with Azure OpenAI and Azure AI Search, and built complex data pipelines with Azure Data Factory and Azure Service Bus. In addition, there is classic backend development in C# and Blazor, as well as enterprise-level Oracle database development. A specific example: an AI-powered protocol generator that automatically processes Teams transcripts and plays them back to users in real-time via SignalR. I use AI not as a toy, but as a productive part of a workflow.

In addition to my main job, I developed Habjour, a habit tracker specifically for neurodivergent people, which is now available on the App Store and Google Play. The app originated from a personal experience with my son and was designed to be accessible from the start, with Mistral AI integration and full GDPR compliance. I developed and published it alone, in my free time. You can see the result at habjour.com.

I work remotely, think along, and don't disappear when things get complicated.
