Solo — product, curriculum tooling & engineering · 2026

A guided, gamified language-learning app — five courses across Spanish, French, Japanese, Korean and English, each following its own national framework end to end.

• One JSON-driven runner renders all 15 exercise types; grading applies per-language tolerance passes — accents (ES/FR), spacing (KO), kana (JA) — instead of marking near-misses wrong.
• No language is hardcoded anywhere in app logic: courses, levels and units all flow from the data model, so a new language is content plus a seed script.
• Live voice tutor on Gemini's audio Live API, with short-lived tokens minted server-side so the API key never reaches the browser.
