About me: I am a Full Stack & Data Engineer based in Enzersfeld near Vienna. I take full ownership of data engineering and full-stack work, turn ideas into working products, and speak up when something is off. I have been coding since I was 12.
Since July 2018 I have run koveh.com, an IT consultancy for data engineering and full-stack development with a team of 2-5. Clients include APA Austria, ÖAMTC, Lenzing, the David Krems Institute, and FMCG and real-estate companies. I have also built my own products: a speech-to-text service (2,000+ users), a dietary app (5,000+ users), a restaurant CMS and an investment platform.
Selected work:
- Realcube (since May 2026): rebuilt the data architecture and ETL pipelines of real-estate management software used by Lidl and 60+ companies, fixed data quality, added observability, and prepared data for MCP and an AI chatbot. Built a CRREM decarbonisation-tracking system.
- UNIQA Insurance Group (2024-2026): RAG chatbot and OCR research with VLMs, RPA and LLM-agent data collection, customer-service automation, a cross-platform screen-translation app, and classification of 120k medications.
- KPMG (2022-2024): a data warehouse and ETL pipelines in Azure Data Factory for the audit department (2,000+ employees), BI dashboards and APIs; later a RAG chatbot for Verbund and an ESG reporting tool.
