👋 Hi, I'm Ralf Becher

Founder & Head of R&D at RALFORION, based in Veli Lošinj, Croatia. I build intelligent data platforms that combine ontology-driven analytics with modern semantic layer technology.


🚀 About Me

  • Building OrionBelt Analytics — an ontology-based analytics platform
  • Passionate about semantic data modeling, knowledge graphs, and BI architecture
  • Long-time contributor to the Qlik community with extensions and open-source tools
  • Arctic Code Vault Contributor

🦾 Technologies & Tools

JavaScript TypeScript Python Go Node.js Docker Neo4j Qlik

Snowflake Databricks ClickHouse DuckDB

LangChain LangGraph MCP

RDF OWL

Agentic AI Semantic Layer


Featured Projects

Ontology-driven analytics platform for AI agents — transforming how data is modeled, explored, and understood through knowledge graphs and semantic reasoning.

A universal semantic layer that bridges the gap between raw data and business meaning, enabling consistent metrics and definitions across tools and teams, designed with an API-first approach for agentic AI.

A Streamlit-based application for building, editing, and managing OWL ontologies — providing a visual interface to define classes, properties, and relationships for semantic data models.
