Profile
LLM Engineer and BI Developer with 5 years building production data and AI systems on the Microsoft stack — Navision ERP, Azure, and Power BI — inside a German healthcare company. Designed and shipped an Azure Functions application using GPT-4.1 and LangChain that automates document classification, indexing, and case summarisation against an Enaio DMS, processing ~100 medical documents per day at 85% accuracy and reducing per-document handling from 30 minutes to seconds. Delivered 20+ Power BI dashboards across 8 departments, integrating Navision, Enaio, and HR data, including reporting that turned a 3-day manual bonus calculation into an instant view. Co-author on three peer-reviewed healthcare publications, comfortable translating clinical questions from non-technical doctors into SQL, dashboards, and AI workflows. Based in Arnsberg, German B1 (advancing to B2), moving toward technical team leadership in AI-for-enterprise.
Experience
- Built Azure Function App (GPT-4.1, LangChain) automating classification, indexing, and case summary extraction for Enaio DMS — ~100 documents/day at 85% accuracy, reducing handling from ~30 minutes to seconds.
- Applied deliberate model selection: GPT-4.1-nano for OCR pre-processing, GPT-4.1 for complex reasoning — optimising accuracy vs. API cost across document types (Verordnungen, AU, OP-Berichte, Rechnungen).
- Currently building a document privacy filter using an open-source LLM to redact sensitive patient data before cloud processing — privacy-by-design in healthcare AI pipelines.

- Integrated Microsoft Navision ERP, Enaio DMS, and Microsoft HR into a unified cross-departmental reporting layer.
- Bridge between non-technical clinical staff (doctors, department heads) and data infrastructure — translating domain requirements before writing a single query.
- Extract datasets via complex SQL (CTEs, multi-table joins) from Enaio DMS; deliver full analysis pipelines with clinical research reports.
- Enaio DMS fundamentals, ETL workflow design, foundational Power BI reporting.
- Helpdesk lead for 1,000+ employees; achieved +15% system uptime improvement.
- Smart City project (District 6): delivered 10% utility cost reduction; built SQL/Elastic dashboards reducing reporting time by 20%.
