su3-hokkaido

Based in Asahikawa, Hokkaido. Into mountaineering, backcountry skiing, nagauta shamisen, and half marathons. By day, I work as an IT engineer.

What I do

I make my living mainly as an EM/PM, and now and then support companies on a contract basis or perform on the shamisen.

  • Backcountry skiing

    Started in 2022. Around 90 trips in total by the 2025-2026 season. Mostly in northern and eastern Hokkaido, skiing the local hills from December to May.

  • Mountaineering

    Started in 2019. Around 70 trips in total by the end of 2025. Mainly climbing in the Daisetsuzan range of Hokkaido.

  • Marathon

    Started in 2023. From spring to autumn, I run in local community marathons now and then.

  • Shamisen

    I play nagauta and debayashi. On request, I also perform at day-care facilities and amateur rakugo events.

  • Engineer

    From a major Japanese SIer to a local Vietnamese company to a Japanese SaaS, I have mainly worked as an EM/PM. For personal projects, I mostly build mobile apps just the way I like. Tech I often use: - Flutter, Laravel, Golang - Next.js, Vue.js - MySQL, PostgreSQL - AWS, Cloudflare, Vercel, Supabase
