Senior Data & AI Consultant at Philico SA, Lausanne

November 1, 2024 - Present

Engineered and delivered GenAI/RAG platform components for a regulated AI fintech, including internal SDKs, ingestion pipelines, retrieval optimization, agent evaluation, and production quality improvements. Built a RAG evaluation and benchmarking framework using human-verified reference data to compare retrieval methods, ingestion strategies, merging algorithms, and Qdrant configurations using recall, precision, and latency—guiding changes to production RAG quality. Delivered production AI agents such as a structure-preserving document translation agent and a multimodal RAG assistant for assembly-line operators, focusing on faithfulness, hallucination detection, and citation validation. Also contributed to applied ML for Geneva Airport, including per-flight passenger forecasting at about 80% accuracy and a demand-capacity decision-support tool to reduce operational congestion.
