Technical Leader, Platform Architect, AI Researcher

Engineer and entrepreneur building Zetesis, a RAG-as-a-Service SaaS platform for AI-powered document exploration. Deep experience in GitOps/Kubernetes infrastructure, Python/FastAPI backends with AI integrations, and modern React/Next.js platforms. I build and operate end-to-end systems—from declarative infrastructure with ArgoCD and Talos Linux to DDD+CQRS backends with multiple AI providers and type-safe frontends. Passionate polymath with broad interests spanning technology, economics, and history. My applied research explores knowledge-graph-augmented retrieval (KG-RAG) and agents as instruments to assist research, with a particular interest in the Austrian School of Economics and liberal thought.
