ICT Chatbot (Work in Progress)

Solo

ICT Chatbot is an AI and RAG powered chatbot that provides information about ICT-related topics and course information to students. The chatbot is built using PostgreSQL and PGVector for data storage and retrieval, and it utilizes OpenAI's GPT-4 model for natural language understanding and generation. The chatbot is designed to assist students in finding relevant information quickly and efficiently, enhancing their learning experience.

Go Exchange

Team

Go Exchange is a web application that connects students interested in exchange programs with people who have already participated in such programs. The platform allows users to create profiles, share their experiences, and find potential exchange partners. Users may find important dates and information considering the application process and support that comes with it. OpenAI AI-Chat integration has been added to enhance user experience. Instead of using OpenAI's vector store, we implemented a custom vector store using Milvus to store and retrieve exchange related documentation which I was responsible of along other tasks.
