Hi! I am Han Lee.
I build and operate machine learning systems. Currently I am building and operating Generative AI applications, search and discovery systems, and LLM models.
In this blog, I journal my thoughts on machine learning engineering, data science, and MLOps.
Occassionally I might write about the technology industry as someone who has sell-side, buy-side, and venture capital investing experiences in the tech sector.
