Freelance Software Architect, Full-Stack Developer, and founder of crosslabs GmbH from Germany. I build scalable platforms and modern business applications with .NET, Angular, Event Sourcing, CQRS, AI integrations, and distributed systems. My current focus is on realtime AI applications, voice interfaces, and flexible architectures supporting local deployment and bring-your-own LLMs. Here I share thoughts, experiments, architecture ideas, and lessons learned from building complex software systems, SaaS platforms, and AI-driven products.
