Job Description
Role Overview
This role is focused on building a mobile-first SaaS MVP designed to streamline youth sports scheduling for families with multiple children. The application will enable parents to register, create family profiles, add children and teams, manually input events, and leverage AI to extract event details from team messages or uploaded schedules. Parents will confirm or edit extracted information before it is saved to a centralized family calendar. The platform will also feature a family dashboard, an AI assistant for schedule queries, basic conflict detection, email reminders, Stripe-powered subscriptions, free-plan limitations, account deletion, analytics, and production deployment. The ideal candidate will architect and deliver a simple, reliable, and responsive web application, avoiding unnecessary complexity and focusing on core functionality.
