I'm a Data Scientist & AI Engineer based in Hamburg. Five-plus years at OTTO Group as a Bilanzbuchhalter — SAP FI-CO/BPC, IFRS/HGB, UiPath RPA — then a deliberate pivot into ML/AI. Today I build end-to-end AI systems: multi-agent LLM pipelines, deep-learning vision, RAG, full-stack web on AWS.
- Finishing my M.Sc. thesis at FH Wedel — Document Intelligence and Knowledge Graph Construction: OCR-free extraction with modern document VLMs, entity resolution, GraphRAG reasoning over local LLMs. Fully local, zero cloud.
- Working through AWS Cloud Practitioner, AI Practitioner, and ML Engineer Associate certifications.
- Shipping cloud-deployed ML projects on AWS CDK.
- LLM-powered systems — multi-agent apps (Agno / LangChain), crawlers, RAG, structured outputs with Pydantic
- Deep Learning for Computer Vision — ViT, DINOv2, ConvNeXt, ResNet-50, Grad-CAM / Attention Rollout
- Classical ML — bankruptcy prediction, recommenders, time series, econometrics
- Full-stack web — Next.js 16, React, Spring Boot, FastAPI, AWS CDK, Tailwind v4

Six months of commits, lifted into an isometric calendar — and a chibi web-slinger parkouring across the rooftops, sector by sector. Updates daily.
Flagship projects are pinned above — multi-agent LLM pipelines, deep-learning vision, recommenders, full-stack apps. The table below highlights additional work that complements the pinned grid.
