Yuri Koshiishi
Web Developer & Producer
東京-based developer who enjoys building things - web, mobile apps, whatever needs building. Always learning something new.
About
I build digital solutions that solve real pain points - whether that's creating smoother user experiences, optimizing performance, or just making complex workflows simpler for people to navigate. There's something satisfying about writing code that actually does what you want it to do.
Most of my work is frontend-focused, where the details really matter. Clean, maintainable code is non-negotiable, but so is getting the UX right - those small interactions and transitions that make an app feel polished rather than clunky. I also enjoy diving into mobile development when projects call for it.
