About#

I’m Ryuki Maruyama. This blog is where I write down what I’ve actually tried and figured out, from Linux, networking and web app development to car coding and vehicle registration paperwork in Japan.

I work as a web engineer, currently building a SaaS used for selling auto parts. Cars are also a hobby that got out of hand: I obtained a secondhand dealer license (kobutsusho kyoka) and I’m a member of used car dealer auctions.

My career and licenses are on the company page at doany.io.

Business#

On the side I run a sole proprietorship, Doa, taking on web development and site building, and consultations around used cars. What I do, what I’ve built and how to get in touch are on doany.io.
