Overview
A platform that generates a population of AI personas with diverse demographic profiles and runs scenario-based world simulations to collect product/market validation signals. It is not just a chatbot — it ties a data pipeline that runs from personas → worlds → simulations → signals, plus 3D persona rendering, a credit economy, community sharing, and automatic IR video generation, into a single product experience.
My Work
- ▸Built the full stack solo on Next.js 16 + React 19 + Supabase
- ▸Reflected a serialization audit into persona CRUD
- ▸Three.js deterministic rendering + WebGL compatibility hooks
- ▸15+ detailed implementation/planning documents · architecture decision records
- ▸An automated IR video pipeline via Remotion
Features
- World creation/detail/diversity analysis
- Console — quick · new · simulation · batch execution
- Signals — summary · statistics · distribution · responses · comparison
- Community — sharing worlds/scenarios/signals
- Credit payment · administrator operations
- Compliance with React 19 hook & purity rules
Highlights
- 3D persona rendering with Three.js + @react-three/fiber
- Regression tests based on Vitest + RTL + MSW
- Chrome headless E2E smoke
- Automatic IR video generation with Remotion
- Credit economy · administrator operations features
