Founder & Head of R&D at RALFORION. Building semantic layers and ontology-driven analytics β€” so AI stops guessing your GROUP BY.


Tip

Currently working on: The OrionBelt ecosystem β€” ontology-driven analytics with a universal semantic layer and visual ontology builder, designed for agentic AI workflows. Because data deserves better than copy-pasted SQL.


πŸš€ About Me

  • Building OrionBelt Semantic Layer, OrionBelt Analytics & OrionBelt Ontology Builder β€” because data deserves better than copy-pasted SQL
  • Semantic data modeling, knowledge graphs, and BI architecture β€” the stuff that makes dashboards and Agentic AI actually trustworthy
  • Longtime Qlik community contributor β€” extensions, open-source tools, and opinions nobody asked for
  • Longtime Gopher 🐹, now addicted to snakes 🐍
  • Arctic Code Vault Contributor β€” my code will survive the apocalypse, no pressure
