I am an AI Product Engineer focused on building production-ready mobile and full-stack applications, especially products involving LLMs, real-time voice, speech AI, and React Native.
I have independently designed, developed, deployed, and shipped multiple real-world products, covering the full lifecycle from architecture and frontend development to backend APIs, AI integration, cloud infrastructure, subscriptions, and App Store release.
Core expertise
• React Native, TypeScript, JavaScript, Node.js
• iOS and Android application development
• React Native native modules and platform integrations
• LLM and Generative AI integration
• OpenAI-compatible APIs, Qwen, DeepSeek and multimodal AI
• AI Agents, structured LLM output and AI-powered product workflows
• Real-time speech recognition, STT, TTS and speech-to-speech translation
• Real-time audio streaming and WebSocket architecture
• Voice AI and conversational applications
• REST APIs and backend service development
• Cloudflare Workers, Edge Functions and serverless architecture
• Object storage, CDN and cloud delivery infrastructure
• Authentication, subscriptions and In-App Purchases
• App Store deployment and production debugging
• React Native OTA / application update infrastructure
Selected product experience
• Built an AI keyboard with real-time speech input, text generation, rewriting and AI-assisted communication.
• Developed a real-time voice translation solution using streaming speech and AI APIs.
• Built an AI-powered manga and image translation browser using multimodal models.
• Developed an AI food recognition and nutrition tracking mobile application.
• Built React Native OTA update infrastructure including SDK, backend services and cloud distribution.
I am particularly effective on projects that combine multiple technical areas, such as mobile apps + AI + backend + real-time audio. I can take an existing prototype or product idea, design the technical architecture, implement the required systems, integrate AI models, solve production issues and prepare the application for real users.
