Hi! Welcome to my site.

I'm a data scientist working at the intersection of messy real-world data, scientific questions, and systems that have to run in production. Most of my work involves building LLM pipelines for clinical NLP, designing data infrastructure, and turning complex research problems into usable tools.

I like understanding how things work under the hood — whether that's a model, a pipeline, or a dataset. This site is where I share projects, experiments, and ideas that sit at that intersection.
