About

I’m Genki, a builder based in Tokyo, currently leading engineering at EastWest Developers across the US and Japan.

I have 10 years of experience in software engineering, full-stack development, and technology innovation, including 5+ years focused on AI automation and intelligent software solutions.

I help clients and businesses transform complex ideas into scalable digital products, intelligent automation systems, and reliable software platforms. Combining strategic technology leadership with hands-on engineering expertise, I oversee the journey from identifying business challenges and designing technical solutions to development, deployment, and continuous improvement.
