Mobile App & Backend

Contributed as a fullstack engineer to a consumer-facing mobile application for Porsche Digital with real-time video, in-app subscriptions and a serverless AWS backend, delivered within a monorepo setup.

Areas of contribution

• Mobile app: Core React Native features such as onboarding flows, subscription paywalls, favourites and content filtering, with animation and bottom-sheet components.
• Real-time video: Integration of live video sessions and the surrounding UX (screen-awake handling, orientation, transitions).
• In-app subscriptions: Paywall flows, pricing, promotional offers and webhook-based receipt handling.
• Backend: Serverless backend with AWS CDK, Lambda, DynamoDB and API Gateway; user, subscription and session endpoints.
• Web application: Shared components and features between the mobile app and a companion React web app.
• Performance & DX: Data-fetching, caching and build-system improvements; testing setup; type-safety and lint hygiene.
• Analytics & monitoring: Product analytics, error monitoring and event tracking around onboarding and subscription funnels.
