Hi — I’m Estelle :-)

I’m a CS + Computer Graphics student at UPenn.

Before I wrote code, I spent three years in California education policy passing legislation, securing millions in funding, and watching well-designed systems fail because the people who needed them couldn't reach them.

I started coding 18 months ago with the same mindset: making software as navigable as it is honest about what's underneath. In that time I've shipped a museum installation to 180,000+ visitors, led a team of 7 on a 3D ML visualization, and built data pipelines for a utility serving 15 million residents.

My work spans real-time graphics, full-stack engineering, and data — I find the best tool for the problem and learn it. What stays constant is building for clarity: for both the user and engineer reading the code.
