Demirbey

A mobile-first management app built for a sports club. Member records, training schedules, and payment tracking run through a clean app-like interface backed by Supabase.

The Problem

A sports club was managing members, training schedules, and dues the way most local clubs do: on paper lists and in someone's head. Coaches couldn't see who was due at which session, and payment status was a recurring argument rather than a record.

The Solution

A mobile-first club management app with a clean, app-like interface backed by Supabase. Member records, training schedules, and payment tracking live in one place, designed to be used from a phone at the side of the field — not from a desk.

What I Built

• →Member records with status and history in one place
• →Training schedule management per group and session
• →Payment tracking that makes dues a record, not a debate
• →Mobile-first, app-like interface built with Nuxt UI
• →Supabase-backed data layer on a self-hosted Docker deployment

Highlights

• →Mobile-first app UX
• →Member & schedule management
• →Supabase-backed data layer

Outcome

• →Moved the club's daily administration off paper and into one shared source of truth
• →Coaches and admins now work from the same live schedule and member list
• →Designed as an app-like PWA experience that can evolve into mobile packaging when needed
