EVIA

10-agent therapeutic AI platform with layered safety gating and a routing hierarchy. Engineered from Chennai.

Vertex AIGCPmulti-agent orchestrationPython
Problem

01

Build a therapeutic conversational platform where safety is non-negotiable — every user message must pass safety checks before any therapeutic agent acts, and conversations must route to the right specialized agent.

What I built

03

  • 01A 10-agent architecture on GCP / Vertex AI with a dedicated safety-gating layer (A1) screening input before downstream agents act.
  • 02A routing hierarchy (A8) directing conversations to the appropriate specialized agent.
  • 03Built for a use case where incorrect handling carries real risk — so the safety layer is a hard gate, not a soft prompt.
