Multi-agent healthcare ecosystem where a master intent router hands off to specialist agents (diagnosis, CBT wellbeing, triage, nutrition, visualization), including IRIS, a Vision Transformer that predicts systemic risk from a mobile retinal image, and COMPASS, an Agentic RAG insurance guide. Benchmarked on mBRSET, MIMIC-CXR, DeepEyeNet and ROCO.

Communication-support community for text, audio and video. LangGraph.js and Gemini handle clarification, meaning-preserving rewrites and private reading aids; exact text-and-audience approval, critical-slot checks and idempotent publishing keep it safe, and LiveKit powers calls with private AI interpretation.

AI-powered data-intelligence platform that combines NL2SQL, automated ETL, one-click ML pipelines, no-code RAG and auditable agentic workflows.
Stack: Python · FastAPI · React · LangGraph · LLMs · Vector DB
Self-serve analytics tool that turns plain-English questions into governed SQL (NL2SQL) and person-specific dashboards, so ad-hoc reporting no longer waits on the BI team.
Stack: Python · NL2SQL · LLMs · FastAPI · React
Agent-orchestration library that adds a production harness, pluggable memory, observability and evaluation to open-source agentic frameworks, shortening time-to-production across teams.
