Software Engineer based in Japan with 1.5+ years of professional experience, working across full-stack development, system analysis, and bilingual technical coordination.

My primary focus is Java, Spring Boot, React, TypeScript, NodeJs, PostgreSQL, Docker, and AWS. I enjoy building systems end to end — from understanding requirements and designing the solution to implementation, testing, deployment, and technical coordination.

At Meritech Japan, I work across software development and Japanese–English technical coordination. Alongside my professional work, I independently build backend and full-stack systems to deepen my experience in application architecture, distributed systems, testing, and production deployment.

Independently developed an IoT-integrated fall-prevention monitoring system as part of my role at Meritech Japan.

The system provides real-time monitoring, threshold-based alerts, and live data visualization for care-facility staff and was demonstrated at an industry exhibition in Japan.
