What I'm looking for

I’m looking to build and ship real user-facing products end-to-end, owning architecture and compliance. I want to work in Android/Kotlin with strong backend integration, rapid iteration from testing, and room to grow my product thinking.

I’m a self-taught Android developer who independently conceptualised, designed, and shipped Ray Guardian—a full-stack parental control app—from zero to live on the Google Play Store. I built it in Kotlin using Hilt, Firebase FCM, and Supabase, navigating complex technical challenges, real user testing, and Google Play compliance.

On my side of the product, I architected real-time remote commands (FCM push), GPS location tracking with a freshness cache, and per-app daily screen time limits. I also implemented adult content detection using AccessibilityService, GPS/telemetry controls, VPN detection with auto-browser blocking, and a parent dashboard using WebView + native controls backed by Supabase Realtime.
