What I'm looking for

I’m looking for a mobile-first team where I can own architecture and shipping—building reliable backend services, native iOS experiences, and AI-driven features that improve measurable user outcomes.

I’m a Software Developer who likes owning products end-to-end—from architecture to release. At Mentara Fit LLC, I solo-developed a full-stack fitness platform with 70+ mobile screens and 90+ REST API endpoints, handling frontend, backend, and the App Store release pipeline.

I go beyond standard cross-platform workflows when needed. I engineered native Swift modules for Live Activities and interactive WidgetKit widgets, and built HealthKit bidirectional sync inside a bridgeless New-Architecture React Native app.

I also design reliable monetization and user value. I architected a dual-provider billing system unifying Stripe and Apple IAP behind a single entitlement layer with webhook-driven syncing, and I’ve shipped AI-powered meal scanning and timezone-aware analytics in my Mentara Fit SaaS work.
