Principal Software Engineer · Software Architect · Engineering & Transformation Leadership
I work at the intersection of software engineering, architecture, AI, technical leadership and transformation. My focus is on building and modernizing complex systems, aligning technology with business goals, and enabling teams to deliver sustainably.
- Software and cloud architecture
- Distributed systems and modernization
- AI engineering and generative AI
- Engineering leadership and team leadership
- Transformation management
- Stakeholder management
- Developer experience and engineering excellence
Alongside longer-term roles, I am available for selected fractional engagements where experienced technical and organizational leadership is needed without a full-time commitment.
- Fractional technical and project leadership
- Architecture and technology consulting
- Engineering and transformation advisory
- Workshops, training and team enablement
- Stakeholder alignment and technical decision facilitation
This can range from focused workshops and architecture reviews to supporting teams and projects over a longer period as a fractional lead or advisor.
I also build and operate my own SaaS solutions and digital products. This gives me a product and operator perspective beyond consulting and architecture: from product decisions and software delivery to cloud operations, automation, cost and continuous improvement.
One of these products is Traumliga, a platform for interactive games and business applications. I use these products to explore and apply modern software architecture, AI, cloud-native engineering and product development in real operating environments.
