The work

An EdTech startup needed a real-time AI tutor — a 3D avatar that teaches kids French by talking with them. We designed the full architecture connecting a React front end, a Python back end and an Unreal Engine avatar into a single real-time pipeline: the LLM handles language, TTS/STT handles voice, and face tracking drives the avatar’s expressions.

It was built modular from day one, so new agents can launch without rebuilding the core — the engineering decision that turns a demo into a product.
