At JULO, I led frontend architecture improvements and the JULO Web App v2.0 upgrade. I built an internal preview deployment tool with GitHub Actions and Google Cloud Run, reducing infrastructure cost from about $20 per developer to $5–10 for the entire team.

I also built reusable components and maintained a Storybook-based design system with React, TypeScript, and Emotion.js. I reduced application bundle size by 38% and mentored frontend engineers through code reviews and technical coaching.
