Freelance IT engineer from Hokkaido, Japan.
Always learning. Always improving.
About Me.
I’m a freelance IT engineer with over 10 years of professional experience across a wide range of fields — including software development, cloud infrastructure, server and network management, cybersecurity, web technologies, operations, and AI development.
I'm a curious and adaptable problem-solver who thrives on new challenges and loves learning emerging technologies. My hands-on expertise spans not only programming, but also designing secure cloud environments, developing AI-powered solutions, and contributing to open-source projects.
Currently based in Japan, I’m looking to expand my career globally — particularly into the U.S. tech industry — and I’m open to remote opportunities and collaborations with international teams.
I take pride in delivering practical, creative solutions tailored to diverse technical needs, backed by a broad and deep technical background.
Let’s connect and build something impactful together.
