Inspiration

In Cai Mon, Ben Tre - Vietnam's flower capital, SMEs lose 70% of time to manual tasks. From flower shops in Cho Lach to small factories, owners work 16 hours but still can't scale. We asked: What if AI agents could run the business for them?

What it does

NUCLEUSNEXUS is an autonomous AI workforce platform where 5 specialized agents collaborate 24/7:

  • Sales Agent (Gemini 2.0 Flash): Chats with customers on Zalo/Facebook, quotes flowers, closes orders
  • Inventory Agent: Tracks Cai Mon flower stock in real-time via Cloud Vision
  • Logistics Agent: Auto-optimizes delivery routes for Ben Tre - Saigon
  • Finance Agent: Creates invoices, tracks profit with Gemini reasoning
  • Marketing Agent: Generates TikTok content from farm photos

Owner just says: "Bán 100 chậu cúc cho khách Sài Gòn" and the agents execute end-to-end.

How we built it

Built 100% on Google Cloud:

  • Gemini 2.0 Flash & Pro on Vertex AI for agent reasoning and function calling
  • Vertex AI Agent Builder for multi-agent orchestration
  • Cloud Run for auto-scaling agent workers
  • Firestore + BigQuery for real-time SME memory
  • Cloud Vision + Speech-to-Text for Vietnamese flower recognition
  • ADK (Agent Development Kit) for autonomous planning loop

Each agent uses Gemini's long context to remember customer history.

Challenges we ran into

  • Vietnamese dialect for flower names: "cúc mâm xôi" vs "cúc họa mi" - solved with Gemini few-shot tuning
  • Low internet in Cai Mon farms - optimized agents for <2s latency on Cloud Run edge
  • Making agents truly autonomous, not just chatbots - implemented self-reflection loop

Accomplishments that we're proud of

  • 5 agents working together without human intervention for 48h test
  • Reduced order processing from 30 mins to 45 seconds for a real shop in Cai Mon
  • Fully autonomous invoice generation in Vietnamese

What we learned

True agentic AI is not prompt -> response. It's goal -> plan -> tool use -> self-check -> done. Gemini's function calling makes this possible.

What's next for NUCLEUSNEXUS

  • Launch for 100 SMEs in Mekong Delta
  • Integration with Giao Hang Nhanh & MoMo
  • Open-source the Cai Mon flower dataset for Vietnamese AI community

Built for Community Impact

From Cai Mon to the world - empowering SMEs who never had access to enterprise software.
