Intro

I'm Saeed Changiz Rezaei, a Machine Learning Engineer at Meta with a PhD from the University of Waterloo. My career has been a journey through the deep technical layers of AI, from researching quantum-classical algorithms and graph theory to building large-scale systems at AWS and Huawei. I am deeply passionate about Generative AI and LLMs, particularly the power of open-source weights to drive innovation. Beyond engineering, I find immense joy in education—whether I'm teaching linear algebra or mentoring the next generation of AI practitioners through technical labs. I’m here to share insights on complex architectures like RAG and NAS, and I’m always looking to connect with others who are driven by the potential of pioneering NLP advancements to change the tech landscape.
