Rayun Sa Food & Consumer Insights · Data Analysis & Business Strategy

Translating consumer data into actionable business insights across food and service contexts. I combine domain knowledge in nutrition science with hands-on experience in text mining, sentiment analysis, and consumer behaviour research — and I've done it in both Korean and European contexts. My instinct is always the same: find the structural gap in the data, and turn it into something a real organisation can act on.
