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.
