Shopify Developer Needed to Build Training Journal Feature for Fitness Subscription Platform We are building a new feature for our fitness subscription platform pumpandrun.fit, which currently runs on Shopify. Our members access workout videos through their Shopify customer accounts, and we want to add a personal training journal where each subscriber can track workouts and results. The goal is to build a Training Journal inside the Shopify customer account where users can log workouts, track streaks, and see their progress. This is the first phase (MVP) of a larger product, so we are looking for a developer who can build a clean, scalable foundation. Inside the Shopify customer account area, members should see a new section: Features for the MVP: • Add a workout entry • View recent workout history • Track current workout streak • Track workouts completed this week • Simple progress summary Example workflow: 1. User logs into their Shopify account 2. Opens **Training Journal** 3. Clicks **Add Workout** 4. Enters: • workout date • optional note to the workout 5. Saves entry and sees updated streak and statistics. We are looking for a solution that uses: • Shopify Customer Account UI Extension • A custom Shopify app(private or custom app) • External database to store workout entries • Shopify customer metafields for summary statistics Example summary metafields: • current streak • last workout date • total workouts • workouts this week Frontend Customer Account UI Extension inside Shopify account Backend Custom API for storing and retrieving workout entries Database External database (PostgreSQL / similar) Integration Shopify Admin API to update customer metafields The system will later expand to include: • workout calendar • progress graphs • badges / achievements • leaderboards • coach feedback • notifications and reminders So the architecture must allow future expansion.
