27Outs

27Outs is a data-driven baseball analytics product built to help coaching staffs move beyond box scores. The platform ingests granular game events and surfaces advanced metrics — pitch velocity trends, situational performance, and player comparisons — in dashboards designed for fast decision-making during and after games.

Coaching staffs often rely on delayed, aggregated statistics that don't reflect in-game context. Pitch-by-pitch data exists but is difficult to access, interpret, and act on without dedicated analytics tooling.

27Outs centralizes game event data into a purpose-built analytics platform. Coaches can filter by situation, compare players across metrics, and identify performance patterns without exporting spreadsheets or waiting on manual reports.

• —Pitch-by-pitch event ingestion and normalization
• —Advanced metric calculations (velocity, spin, situational splits)
• —Interactive player and team comparison dashboards
• —Responsive layouts for desktop and tablet sideline use
• —Export-ready reports for post-game review

Client-server architecture with a React/Next.js frontend, API layer for metric computation, and PostgreSQL via Supabase for structured event storage. Server components and edge deployment on Vercel keep dashboard loads fast.

Relational schema organized around games, innings, at-bats, and pitch events. Indexed query paths support filtering by player, date range, and pitch type. Aggregated views pre-compute common coaching queries.
