Aurynix Nexus — AI Business Assistant

A multi-agent assistant built with FastAPI and LangGraph that routes work between research, email and calendar agents — with a human approval gate before any irreversible Gmail or Calendar action.

  • RAG pipeline on Qdrant + FastEmbed with heading-aware chunking, OCR fallback and source/page citations
  • Regex-first supervisor routing with LLM fallback; async ingestion through a Redis worker queue
  • OAuth 2.0 with PKCE, AES-256-GCM token encryption and refresh-token rotation
  • Live SSE streaming backed by 282 automated tests; OpenTelemetry, Prometheus and Sentry monitoring

Competition · DataCamp × Gaza Sky Geeks

Pink AI Hackathon — 1st Place

Team Rooters won a three-hour breast cancer data science challenge in DataCamp's Pink October program — framing the model as a tool that supports doctors, not one that replaces them.

  • Repaired hidden errors in a messy, hand-typed dataset instead of deleting data
  • Removed a leaking feature and chose a decision threshold we could defend
