About CourtViz

CourtViz was created as a sports analytics project to deliver powerful insights across all levels of sports and competition. The first step was launching a full-stack website to showcase the entire analytics pipeline — from back-end data collection and storage to front-end interactive visuals.

Features include dynamic player dashboards and a Player Finder tool that helps identify undervalued players and uncover strengths and weaknesses based on data-driven metrics. The vision is to expand across multiple sports while refining tools that support performance analysis, roster construction, and scouting.
