Problem

Users wanted a wellness companion that felt personal and supportive across chat and voice, with reliable accounts, subscriptions, and data sync—not a static content library.

Solution

Owned end-to-end delivery: SwiftUI app architecture, OpenAI GPT assistant flows, ElevenLabs voice AI, Firebase Auth and Firestore with Cloud Functions, GCP-backed APIs, RevenueCat subscriptions, push notifications, analytics, and App Store launch.

Solution Architecture

SwiftUI client talks to Firebase and GCP-hosted services for AI orchestration. GPT handles structured dialogue and personalization; ElevenLabs streams natural voice responses. Cloud Functions enforce auth, quotas, and webhook handling for subscriptions.

Mobile + Backend Design

SwiftUI navigation and state for onboarding and journey flows; Firebase Auth for identity; Firestore for user profiles, conversation history, and journey progress; FCM for re-engagement pushes.

AI / Python Services

Server-side prompt and context assembly for GPT, with safety and length limits before responses reach the client. Voice requests routed to ElevenLabs with caching for repeated phrases where appropriate.

Technical Challenges

Balancing latency for voice playback with conversation continuity, keeping subscription state consistent across StoreKit, RevenueCat, and Firestore, and designing journeys that adapt without overwhelming new users.

Outcome

Launched a production iOS wellness product with conversational and voice AI, monetization, and cloud infrastructure built to scale with user growth.
