At Visualutions, I authored 98% of the commit history on Saber, a 120,000-line React and TypeScript analytics and compliance application. I set architecture and code quality standards across 30 modules, built a shared design system, and integrated more than 230 REST API endpoints behind OIDC single sign-on.
On SportAppV2, my tennis forecasting project, I improved database query patterns, designed a nine-table PostgreSQL schema, and built a React client and admin console. I also built a walk-forward cross-validation harness to report model metrics and calibrate conditional probabilities.
