I am primarily responsible for the Navi Chatbot product, integrating the AWS cloud platform and Bedrock LLM to provide RAG-based Q&A services for various file types, including MP4, MP3, PDF, and more. I use Langchain, VectorDB, FastAPI and other tools for system integration.

I worked as an intern in the Big Data Office of Foxconn Technology Group, where I undertook machine learning and AI-related projects, specifically in the areas of NLP or emotion systems (such as public sentiment analysis). I used a Siamese-LSTM network to determine the degree of support for corresponding events based on news articles.
