About
MSc Business Analytics student at UCL with a background in Computer Science & Mathematics (UW-Madison) and Operations Research (UEC Tokyo). I work at the intersection of data science, AI, and product, from building ML pipelines and analytics dashboards to multiplayer web games. Trilingual in English, Chinese, and Japanese.
Projects
A selection of things I've built and explored.
OrderThis
OngoingGenerative AI startup project helping travelers navigate foreign-language menus. Built a Streamlit MVP with Gemini API for multimodal menu understanding, allergen inference, embedding-based RAG, and a 4-tier image fallback pipeline. Collaborated on market analysis, customer segmentation, and competitive differentiation, defining a B2C-to-B2B growth model with a data flywheel strategy.
Interactive Industry Analysis Assistant
An interactive research assistant that converts an industry query into a structured LLM-generated market research report from automatically retrieved sources, with input validation and sub-30-second delivery. Features disambiguation filtering and fallback querying for robustness, plus an enterprise deployment framework with source whitelisting and latency monitoring.
