Built and optimized GenAI data pipelines supporting large-scale document processing and RAG applications. Designed a cache-first prompt architecture, task-based model routing, deterministic validation guards, automated ingestion, and machine-checkable quality controls. Processed 9,000+ source documents and produced 4,000+ RAG-ready Markdown documents. Reduced measured LLM inference cost by ~90% through call reduction, caching, routing, and deterministic validation while maintaining automated quality checks.

Developed a digital twin for a European FMCG client to improve demand forecasting, inventory optimization, and anomaly detection. Simulated multi-source data including sales, inventory, weather, and customer sentiment for machine learning training. Built XGBoost demand forecasting models using pricing, promotions, and sentiment as external drivers. Implemented EOQ and Deep Q-Network (DQN) approaches for inventory optimization, achieving over 95% service level while minimizing costs. Designed anomaly detection for demand, inventory turnover, forecast errors, service levels, and cost deviations. Built the solution using Python, Pandas, NumPy, Matplotlib, Scikit-learn, LLMs, Selenium, FastAPI, React, Docker/Podman, and Azure. Containerized and deployed the application dashboard to Azure for real-time accessibility.
