What I Build

I turn narrow, repeated workflow friction into polished web products: AI translation that stays in context, local media utilities that avoid uploads, developer tools that clean up the boring parts, and edge-first React apps that are fast enough to feel native.

AI-assisted workflow design - AI appears only when it removes a real step.
Privacy-conscious browser tooling - translation, reading, and browsing tools that stay close to the page.
Client-side media processing - FFmpeg.wasm and local-first flows for creator work.
Edge-first full-stack React - Cloudflare Workers, D1, R2, and React Router for small, sharp apps.
Readable technical writing - notes about shipping products, web development, AI tooling, and product decisions.
