Hey, I'm Marcel
Software Architect. Founder. Product Builder.
I design and build digital products end-to-end — from concept to scalable production systems.
Mobile applications. Cloud-native backends. Automation pipelines. Clean architecture.


Design.
From idea to structured product concept and scalable architecture — defining clear scope, clean UX and deliberate technical decisions.

Build.

Operate.
Deployment, monitoring and continuous optimization of production systems to ensure stability, performance and predictable operating costs.
