Wang H.

I am a Mobile AI Systems Architect specializing in building high-performance mobile applications, real-time AI systems, and scalable backend architectures. I help companies design and build complete production-ready systems — from mobile apps to backend infrastructure and real-time AI interaction layers. My focus is not just on writing apps, but on engineering full systems that integrate mobile, backend, and AI capabilities into a seamless product. 📱 Mobile Engineering (10+ years) • iOS (Swift / SwiftUI / Objective-C) • React Native (including Native Modules) • Capacitor (web-to-native hybrid applications) • Published 20+ apps on the App Store 🧠 Backend & System Architecture • Golang (high-performance REST APIs, WebSocket, authentication systems) • PostgreSQL / MySQL / Redis • Scalable backend architecture design • Real-time system development 🤖 AI & Real-time Systems (Key Differentiator) • Real-time voice AI systems (Speech-to-Text + Text-to-Speech + LLM streaming) • WebSocket-based low-latency communication pipelines • Integration of LLMs (Claude / GPT) into mobile applications • AI-powered conversational interfaces • End-to-end voice interaction systems 🌐 Web Development (Supporting Layer) • Next.js, React, TypeScript • API-driven frontend applications • Web-to-mobile transformation (Capacitor / hybrid apps) 🛠 DevOps & Cloud Infrastructure • Docker, Linux, CI/CD (GitHub Actions) • AWS (ECS, S3, Route 53, ECR) • App Store / TestFlight deployment • System monitoring & production deployment 🚀 What I Focus On • Building end-to-end mobile + backend + AI systems • Real-time and low-latency application architecture • Complex integrations (mobile apps + backend + AI services) • Turning ideas into production-ready systems, not just prototypes • Fast iteration with clean, maintainable architecture 💡 Typical projects I work on: • AI-powered mobile applications (voice assistants, chat systems) • Real-time communication systems (voice / messaging / streaming) • Mobile apps with Golang backend systems • Cross-platform applications (iOS / React Native / Capacitor) • MVPs and scalable system architecture design If you are building a mobile product that involves AI, real-time communication, or complex backend integration, I can help you design and deliver a complete production-ready system.
