About Amadeus

From Chaos to Clarity: Architecture that Scales – with System.


I help software agencies and internal product teams scale faster and more independently – with modern software architecture that relieves rather than hinders.
My focus: Software modernization, Cloud Native Apps, AI integration, and architectures that deliver measurable added value – from day one.

With over 8 years of experience in .NET, full-stack development, Microsoft Azure, and scalable systems, I don't just develop concepts, I build architectures that make your team immediately more productive.

💡 What sets me apart
I am not an architect who delivers slides.
I am your technical partner who thinks along, builds along, and takes responsibility along – as CTO-as-a-Service or architect in the project.

I deliver:
- Productized architectures that work immediately
- Scalable systems that grow with your team
- Structure and clarity – instead of chaos and dependencies

🔧 Experience (Selection)
- Monolith migration to Azure Functions & event-driven microservices
- Building observability solutions with OpenTelemetry & Grafana
- Introduction of AI Agents into existing product landscapes
- Architecture setups for scaling teams in logistics, e-commerce & SaaS

🚀 My Offer
1. Cloud Scale Starter Kit (free): Plug & play setup for .NET & Azure – incl. observability & load tests
2. Architecture Audit: Clear analysis of your architecture & processes – with concrete recommendations
3. CTO-as-a-Partner: Technical sparring at eye level – without a permanent CTO

Team support via Vitera (own product): Access to verified developers & specialists, flexible and without overhead


🎤 Conferences & Talks
I regularly speak at tech events about:
- Event-driven architecture that scales
- How architecture enables – or hinders – growth
- Developer enablement through systems thinking & clarity
