I developed the full mobile and backend infrastructure for HeySiM, a marketplace for digital eSIMs.
Direct-to-Code: Built the MVP in 30 days using React Native and Lovable, skipping static prototyping.
eSIM Access API: Deep integration for real-time catalog fetching and instant profile generation.
Dual-Payments: Integrated Stripe (Web) and RevenueCat (In-App) for seamless credit-based purchases.
Instant Delivery: Custom logic for users to buy credits and receive an instant QR Code for eSIM activation.
Store Success: Managed full publishing and compliance for Apple App Store and Google Play.
