Bilingual Full-Stack Developer Building Practical Tools for Real-World Workflows
JavaScript, TypeScript, Node.js, Python, UI tooling, measurement workflows, internal tools, and customer-facing product thinking.
I build practical web tools that solve workflow problems. My background in bilingual customer operations and ICT teaching strengthens my ability to understand users, communicate clearly, and ship software that is usable in real business contexts.

Beyond code
Operational intelligence
Bilingual communication that helps products land
English and Japanese communication supports work across customers, operations teams, and engineers, which is especially valuable for Japan-based product and support-tech roles.
Customer-facing workflow understanding
Experience around Shopify, Gorgias, issue resolution, and day-to-day operations improves judgment about what users actually need software to do.
Technical teaching and clear explanation
ICT teaching experience strengthens technical communication, demo-building, and the ability to explain implementation details to non-experts.
