What it is
Poliglotter transforms the pages you already read into a language-learning surface — inline translations, spaced-repetition vocabulary capture, and contextual practice, without breaking your reading flow.
My role
I co-founded Poliglotter and owned the fullstack build: the extension (content + background scripts), the shared TypeScript type layer, and the backend sync API. I took it from an empty repo to a shipped Chrome Web Store product and a startup contest finalist.
Highlights
- Real-time page parsing without dropping frame rates.
- Shared TypeScript types across extension and backend — one source of truth.
- Validated with users, not just built in a vacuum.
