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.

Just built my first native macOS app (with zero dev experience)
Stack: Claude Code + Xcode + Figma (for the app icon design only)
The app is nothing special really - just another pomodoro/focus timer, but the fact that it's my first experiment with Xcode and it took just a few hours, makes me super excited.
I'm now setting up an apple developer account and brainstorming what to build next 😅
I’m genuinely glad I had the opportunity to try @Figma Make in the latest @Contra HQ challenge - even I was surprised by the final result.
I created an interactive, immersive experience with customizable colors and unique sound effects designed to support mindfulness and stress relief.
Visually, the outcome is clean and refined, with carefully placed staggered animations and transitions enhancing the overall flow.
If you need a few minutes to reset, I recommend trying the breathing exercise on the site - I hope it helps you get through a long day.
