Hi, I’m Cho Sung Woo, a full-stack integration engineer who builds AI-powered enterprise solutions. I’ve delivered end-to-end chatbot integrations for clients such as Hyundai Department Store Group, Sejong City Government, and Persis Group by wiring Kakao i Open Builder and Skelter Labs AIQ into client systems. I’ve gradually expanded into LLМ-native mobile development with a focus on practical, scalable products and enjoy turning complex requirements into reliable software. Recently I launched Trove Way, a travel memory app, as a solo project on the App Store, focusing on end-to-end development with React Native, Supabase backend, Gemini API integration, and App Store deployment. I’m open to relocation within Canada and to remote roles.
