Yixin's Portfolio

Hey! I'm Yixin ("Isshin", 毅鑫) Tian, a computer engineer and data scientist based in Toronto, Canada. I specialize in designing and building scalable ML systems by bridging software engineering with ML techniques.

Currently, I'm working as a Data Scientist at RBC, focusing on ML infrastructure, including deploying the open-source Dagster orchestration platform on OpenShift and building event-driven inference + monitoring pipelines. I'm also exploring Retrieval-Augmented Generation (RAG)-based AI assistants tailored for banking. Outside of work, I'm a part-time researcher at the University of Southern California's Information Sciences Institute (ISI), researching agentic structured data extraction and knowledge graph technologies.

My passion lies in exploring better modes of knowledge sharing that can increase the communication bandwidth between humans (and AI) in education. When I'm not coding or researching, I like running, writing blogs, reading, or hiking in nature.
