React Native & iOS Developer | AI Agent Developer | Fractional CTO

React Native and iOS apps that stay live, scale, and handle the hard edge cases - offline sync, hardware integrations, real-time dispatch. I build production mobile software and AI agents for product founders who need honest scope and shipped milestones. Ten years of native mobile work across both platforms, twice stepping into a CTO seat to inherit broken codebases and ship through them. I also build AI agents daily - not as a side interest, but as production tooling I use and publish. That combination of deep mobile craft and applied AI is uncommon on one profile. 📱 React Native + Expo — production apps on both stores, hardware integrations (Stripe terminals, Bluetooth printers), offline-first architecture 🍎 Native iOS - Swift, SwiftUI, AVFoundation, CoreLocation, StoreKit, SwiftData 🤖 AI agents + LLM - MCP, structured JSON output, eval-driven prompt engineering, streaming reasoning display 🔍 Diagnostic engineering - file-and-line root-cause reports before any code is touched 🏗️ CTO-level architecture - hiring, release pipelines, greenfield and legacy codebases Xola Phone + Xola Kiosk: React Native B2B tour booking platform serving 170+ agencies, live on both stores with offline transaction integrity and Stripe hardware terminal sync. Ambulnz / DocGo: Native iOS medical dispatch for ambulance crews - real-time multi-driver coordination with CoreLocation, still live on the App Store. Ajaib: Early mobile work on what became Indonesia's largest investment app. Open-source AI agent work: Notion Agent Memory skill (61 downloads on OpenClaw), personal AI coding agent (patched opencode fork) used daily.
