FoundrKids
In pre-launch
An AI maker-learning platform for kids 7 to 15: a chat coach guides build missions while parents track safety.
- I built the full stack solo: three Vue 3 apps, a FastAPI backend with 140+ endpoints, Postgres with pgvector, Redis, and Stripe on Fly.io and Neon, plus an adaptive learning engine.
- Every model call goes through a six-layer safety pipeline: blocklist, OpenAI moderation, prompt scaffolding, the model, a streaming sentence buffer, and a PII-redacting output filter. It fails closed; critical events end the session and alert the parent.
- Cost-controlled model routing sends work to Anthropic or OpenAI by mission tier, with cross-vendor failover and a monthly spend cap per household.
- COPPA is built into the data layer: verified parental consent, a 90-day chat purge, real child deletion, and a tamper-proof audit log.
