Bio

Hoi Zäme! I'm a programmer who enjoys writing software on Gentoo/Funtoo or OpenBSD by day and reading books in quiet by night.
I love greenery and grow vegetables. I recently grow Komatsuna. It resembles Spinach in shape and taste.

I'm originally from Yokohama and grew up in Yokosuka, two harbourside cities located in the Tokyo region of Japan.
However, my soul comes from Zürich and my heart lies somewhere in the DACH countries ;)

Job

Programmer, Software Developer, {Backend,Frontend,Build,DevOps,Platform,Mobile/Desktop Application} Engineer, Developer {Experience,Relations} Engineer and/or Team-Embedded SRE LinkedIn

As a Developer Experience Engineer, I mostly work at the intersection of several positions, such as Backend/Frontend Engineer, Build Engineer, or DevOps/Platform Engineer in recent years.
Through a wide range of development experience of working with various tech stacks, I'm very happy to work with unclear boundaries or in a mixed role. I prefer having practical coding experience. I always try doing things first by myself, even for something unknown. And I'm fully committed to improving the developer experience.

I also have my firm, which is run in my own tiny way :-D
Lupine Software LLC

Patents

As a way of exploring a stable open source business for free software products by making ideas public and considering fair use of anonymised analysis data, I took on the challenge of working on these patents for my own firm.
They have been accepted in Japan and EU, and registered in Japan, Switzerland and Germany. And then, I let them all expire :-D

Supports

I like to support products which help my activities, teams or people who are on their own.
