Hello, I'm Chen Hongji👋, graduating from The University of Tokyo. I'm a Software Engineer with 1 year of internship experience in Tokyo, mainly working remotely. I enjoy programming, gaming, traveling, cooking, and watching soccer. My focus is on Python, TypeScript., and I have experience with LLM and RAG development.
About me
After graduating with an Electrical Engineering bachelor's degree in South China University of Technology, I decided to pursue my passion for programming and dream of studying abroad in Japan. Even thought the coronavirus pandemic was raging, I still quitted my job in order to prepare for the test of Japanese University Master Entrance Examination. And I got admitted to Department of EEIS, The University of Tokyo. My research is about radar and unsupervised machine learning. This experience has deepened my understanding of Japanese culture and broadened my international perspective. My core stack is Python and TypeScript. I am always looking to learn new technologies, e.g.,LLM and RAG. I am currently aiming to become a full-stack engineer.
