At JidouNavi, I co-built and published a vending-machine discovery app for Japan, now live on Google Play. It brings together React Native, Expo, Supabase/PostgreSQL, Mapbox, Zustand, gamification, and English/Spanish i18n.
As a freelance web developer in Tokyo, I ship client products across React Native, Rails, PostgreSQL, JavaScript, and AI-enabled workflows. I also developed field-operations workflows and lead the wzpro.jp web modernization.
At UI Forge, I designed product flows for an AI-powered UI component creator integrating OpenAI, Gemini, and Groq through RubyLLM. I deployed its Rails/PostgreSQL service on Heroku.
My earlier work includes complex field installations under strict protocols at Dewatering Solutions, commercial installations and logistics at Stack It Shelving, and full P&L responsibility across multiple locations at Las Mellis SRL. I use Claude Code in a verification-minded development workflow.
