Alireza Shafaei is a machine learning consultant and exited CTO with a PhD in ML/CV and over a decade of experience shipping production-grade computer vision and retrieval systems at scale. He has built teams 0→1→N, led Skylab through productized ML features to acquisition, and now advises and runs Rezulie Ventures while consulting at Across AI. His strengths span embeddings, retrieval/RAG, re-ranking, model evaluation, and efficient edge/batch inference, with proven experience handling 100M-transaction pipelines and millions of daily images. A pragmatic researcher, he bridges academic rigor and production constraints—publishing work during his UBC PhD while teaching and mentoring engineers. He also contributes to open-source imaging tooling, improving WebP transparency handling in Pillow, which reflects his attention to robustness in real-world systems.
