I am continuously studying English to be able to work with engineers from around the world and handle development tasks in English. My goal is to reach a level where I can work professionally in English within the next two years. I am strengthening my skills step by step, focusing on conversation, reading comprehension, and understanding technical documents.

About Me
I am an engineer based in Osaka, Japan, with expertise across a wide range of areas including front-end applications, server-side development, networking, and infrastructure. I am currently working at an independent systems integrator (SIer).
I have been involved in all phases of the development lifecycle, from requirements definition to post-release operations and maintenance, including architecture design and application infrastructure setup. I have contributed to projects for many well-known companies, building a strong track record of trust and success.
As a project leader on-site, I am involved in mentoring team members, selecting appropriate technologies, and managing quality throughout the development process.
In development, I see my role not just as writing code, but as creating new value and possibilities within systems. I am committed to technical excellence and efficiency, constantly striving to deliver high-level solutions.
My hobbies include winter sports and having BBQs with family and friends. I also enjoy cooking when I'm on my own. I'm into martial arts as well, and I go to the gym regularly to stay active.
I'm not into tech just because it's my job—I genuinely love research and making things. Even on my days off, exploring new technologies and working on ideas is part of my daily routine.
Shall we build the future together?
With flexibility and experience across a wide range of fields including AI, IoT, and OSS, I'm ready to support your next big idea. Feel free to reach out for collaboration or consultation.
