Hi, I'm Raywin Cruz

AI Product Management, SAP HANA Cloud | M.Sc. Data Science @ Mannheim | Applied AI, RAG & ML Systems

I am an M.Sc. Data Science student working in AI Product Management for SAP HANA Cloud, with a focus on applied AI, RAG evaluation, and reproducible machine-learning systems. My work spans multi-agent supply chain optimization, diversity-aware RAG evaluations, and LLM-assisted NLP pipelines.

Featured Work

Project What it solves Key evidence
FMCG Multi-Agent Supply Chain Optimizer Multi-agent decision-support for demand, production, and routing Chronological evaluation, per-SKU model selection and 23 passing tests.
Context Matters — Medical RAG Evaluation Retrieval quality comparison for medical question answering ColBERTv2 best at Recall@5 = 0.751 over 1,000 PubMedQA questions
Economic Framing Annotation LLM-assisted annotation pipeline F1 = 0.811 (Threat) validated against 200-row human gold standard
Discourse Analyzer Cross-platform narrative tracking and analysis FastAPI-based analysis platform locally validated with 31 passing tests and a successful API startup.

Technical Stack

Languages & Core Data: Python R SQL Jupyter

Data Science & Machine Learning: Pandas NumPy Scikit-Learn NetworkX FAISS

Frameworks & Engineering: FastAPI Streamlit Git GitHub Actions

Current Focus

  • 🔭 Current Focus: Exploring reliable agentic workflows and applied AI use cases for enterprise data platforms.
  • Evaluating retrieval components and generation limits in RAG architectures.
  • Engineering reproducible research pipelines using R, Python, and open-source tooling.
