a little about me
じこしょうかいI'm a frontend engineer who's been continuously shipping since 2022. My teammates always said I'm the one who thinks two steps ahead. I write code with the next developer in mind, not just the current deadline.
I'm an engineer first. My foundations are clean React, TypeScript, accessible HTML, and the kind of state and component design that holds up once a codebase gets messy. AI is just one of the tools I use well. I've shipped production features with the OpenAI API and Claude Code, like a quotation parser at G+U and a natural-language task manager. My next focus is deepening my backend skills with the MERN stack and going mobile with React Native.
I'm also the person who'll tell you honestly if something could be built better. Not to be difficult! It's just that, I actually care how the project turns out. (my best ideas usually arrive with a matcha latte)
