Marcel Berger - Apps and beyond

I build production-ready apps – and document how real systems are designed, not just coded.

From first problem definition to architecture, security boundaries, deployment, and monetization. No hype. No “5-day production-ready” myths. Clear systems thinking, real constraints, real responsibility.

With 20+ years in IT, software architecture, and digital transformation, I focus on one question: What does it take to build software that survives reality?

Topics:

– Flutter (iOS & Android)
– Native iOS development with Swift
– Backend architecture with Java, Quarkus & PostgreSQL
– Event-driven systems & messaging
– Kubernetes & operational design
– Security, auth, migrations, monitoring, rollback
– AI integration with standard models
– Monetization with RevenueCat
– CI/CD with GitHub Actions
– Build in Public: DokuAI, Sommelio & PaperlessIQ

Technically solid. Economically sustainable.
