I am a Business Analytics candidate at UC San Diego with a strong finance foundation from Peking University. My work sits at the intersection of business reasoning, technical implementation, and clear communication.
This site is a small portfolio of how I think and what I build. I use it to collect course writing, data analysis, and project work that I want to keep refining over time.
Kelun Wang in a Nutshell
My career is defined by one realization: understanding the business “why” is only half the equation; you also need the technical capacity to engineer the “data how.” That mindset pushed me from traditional finance toward advanced analytics.
I see myself as a translator between strategy and code. Whether optimizing algorithms at ByteDance or automating research pipelines for China Universal Securities, I focus on turning unstructured business ambiguity into structured solutions. I am especially interested in Data Scientist and Business Analyst roles where I can turn large datasets into clear, actionable intelligence.

Why This Site Exists
I believe strongly in the value of open knowledge. Just as the data science community and my experience at UC San Diego have accelerated my own growth, I want this site to be a place where my work is visible, reusable, and continuously improving.
