The Challenge

Deliver a cross-platform medical e-learning application requiring platform-specific purchase compliance across Google Play and Apple App Store, secure proprietary video and document streaming, and enterprise session safeguards.

02

Architecture & State Patterns

• Built with Flutter and Dart using BLoC/Cubit for modular, predictable state management.
• Implemented strict separation of presentation, business logic, and repository layers.
• Designed platform-specific checkout channels isolating Android and iOS payment logic.

03

Backend, APIs & Platform Boundary

• Integrated Stripe PaymentSheet on Android and StoreKit In-App Purchases on iOS, synchronized with backend course access control.
• Integrated VdoCipher SDK for encrypted video streaming with OTP session verification.
• Connected authenticated PDF learning workflows with biometric safeguards and secure token validation.

04

Performance & Data Optimizations

• Currently engineering migration from third-party video hosting to self-managed HLS streaming infrastructure on Hetzner to reduce operating costs.
• Optimized media caching and course asset prefetching for bandwidth-conscious medical students.

05

Verified Outcomes & Production Delivery

• Built the Flutter client from zero through production release on both Google Play and Apple App Store.
• Personally managed end-to-end app store review compliance for both Android and iOS ecosystems.
• Active production product with ongoing video infrastructure enhancements.
