OnDeck Reps

A marketplace concept built with real authentication, profiles, and secure data.

The challenge

Youth baseball players often need extra live at-bats or pitching reps but lack an easy way to find teammates available for impromptu practice sessions. Coordination happens through scattered group texts and word of mouth.

The solution

Designed and built a marketplace platform where players create profiles, post rep requests, list availability, and respond to interest — all backed by Supabase with row-level security policies.

  • User authentication
