With over 5 years of experience as a frontend engineer, I have been involved in B2B/B2C web and app development using React, Swift, and Flutter. I also work as a UI/UX designer, integrating design and technology cross-functionally to create experiences that resonate with users. I handle a wide range of areas, from XR apps utilizing AR/VR, 3D modeling with Blender, to backend development using Laravel and Node.js. I provide comprehensive support across design, development, and business, contributing to solving customer challenges and creating value.

After joining NEC Solution Innovators in April 2023, I was seconded to NEC Corporation in September of the same year, where I worked in the internal DX promotion department and was responsible for 3 new development projects.
In March 2023, I handled the web functionality development and company-wide release of an internal generative AI system. From May 2024, I led the planning, design, and release of a mobile app using Dart/Flutter from start to finish.
Since December 2024, I have been engaged in the operation and maintenance of internal file servers and cloud migration support. As a sub-leader, I provide technical support to the team and mentor members. I am a full-stack engineer with experience in TypeScript/Next.js and Java/Spring Boot development, as well as English proficiency (TOEIC 840, international conference presentations).
