AIM — Live Coaching App (React Native, WebRTC, Stripe)

AIM is a mobile platform for discovering, booking, and joining live online training sessions with professional coaches. The app streamlines session discovery with powerful filters, supports reliable low-latency video calls, and enables seamless in-app payments for both subscriptions and one-off sessions.

Hard to find relevant sessions due to weak filters and scheduling UX.

Unreliable video conferencing, especially on poor networks.

No integrated payment flow for subscriptions or one-time bookings.

Session discovery with multi-criteria filtering (coach, goal, level, time, price).

Real-time availability and scheduling with timezone support and reminders.

Stable WebRTC video sessions with pre-call checks and adaptive bitrate.

In-app payments: Stripe integration for cards, Apple Pay/Google Pay, and subscriptions.

Coach profiles, ratings, and past sessions.

Notifications for booking confirmations, reminders, and reschedules.

Mobile: React Native (TypeScript), React Navigation, Zustand/Redux, React Query.

Video: WebRTC (TURN/STUN), pre-call device tests, network resilience, retries.

Backend Integration: REST/GraphQL APIs, socket events for live session states.

Payments: Stripe (PaymentIntents, SetupIntents), 3DS, subscriptions, webhooks.

Scheduling: Custom calendar with recurring rules, availability windows, cancellation policies.

QA/Release: Jest/RTL unit tests, Detox e2e, Fastlane/TestFlight/Play Console CI/CD.

Analytics/Crash: Segment/Amplitude, Sentry/Crashlytics.

Video reliability on slow networks → Adaptive bitrate, TURN fallback, packet loss concealment, and reconnection logic.
