Founder of Inku
I am an independent software maker based in Calgary. I have been building shipping software for roughly a decade, most recently across small indie iOS projects, internal tools, and a few community newsletters. Inku is my current full-time project.
I started studying Japanese as an adult. I bounced off Duolingo at day 89, burned out on Anki in week three, and ended up building the tool I wished existed. That tool became Inku.
When I am not building, I am reading Kenzaburō Ōe, drinking kōcha, and trying to correct my stroke order. I answer every email to app@inkujapanese.com myself. If you want to talk about Japanese learning, indie software, or small-team design, I am reachable there.
