Full-Stack Developer (Next.js + Supabase + Cloudflare Stream) for Fitness Class Builder App

Summary
We’re developing an internal web app that allows our fitness instructors to build and present classes using a library of fitness, boxing, and kickboxing movements with short demo videos.

The goal is to standardize our workouts and make classes easier to follow for both instructors and members.

We already have a full product spec and UI flow — now we’re looking for a developer to help bring the MVP to life.

Scope of Work

We’re building a web-based app with 3 main features:

1. Movement Library:
• Upload short videos of movements (via Cloudflare Stream or Mux).
• Tag by category (e.g., punch, kick, warm-up, equipment, difficulty).
• Searchable/filterable list view.

2. Workout Builder (Drag & Drop):
• Instructors assemble workouts from the movement library.
• Define sets, rounds, timers, or rest periods.
• Save workouts as templates.

3. Presenter Mode (TV Display):
• Full-screen playback of the workout sequence.
• Shows video, movement name, timer, and “next up.”
• Navigation via keyboard/remote clicker or phone.
