A layer in the canyon wall

PlayVision

Data Science Intern · October 2024 – May 2025

My first startup, deep in the bedrock. PlayVision (YC F25) turns basketball film into analytics, and I worked the unglamorous layer that makes computer vision actually work: precise labeling of game film for model fine-tuning, then collaborating with the data science team to turn model outputs into analytics clients could rely on. I also analyzed market trends to inform the company’s entry strategy. First lesson in data work meaning nothing until it changes a decision.

Freshman-year me learned the lesson every layer above this one is built on: ground truth is called that for a reason.
