TRẦN DƯƠNGThiệu
Fullstack Engineer
AI Agents · Platform Tools
I ship production platforms. From LangGraph agents to theme marketplaces.
I'm Trần Dương Thiệu — a fullstack engineer based in Ho Chi Minh City with 2+ years building production platforms.
Full-time at Onexapis, where I'm primary engineer on Onexbots — a LangGraph-powered conversational AI platform that integrates with Facebook Messenger, Zalo, and more — solo-built the Onex Website builder + theme marketplace including the @onexapis/cli package, and contribute to OnexEOS, our internal ERP covering Ecommerce, HR, manufacturing and more.
I work end-to-end: Python microservices, LangGraph and FastAPI on the backend; Next.js, Tailwind, and shadcn/ui on the frontend. Graduated in Information Technology from HCMUTE with GPA 3.3/4.0.
Outside work — I train calisthenics and box at Happy MMA Club in Saigon (I built their landing too). Code that doesn't ship and bodies that don't move are the same thing to me.

Onexbots
Lead engineer · Onexapis
AI platform that creates virtual staff for businesses — automating customer support and sales. Built on LangGraph with a RAG pattern: a business uploads its knowledge base (PDF, DOCX, TXT, CSV) which is embedded into PostgreSQL + pgvector. The agent then handles conversations 24/7 across Zalo, Messenger, Discord, Slack, and WhatsApp — with grounded, context-aware answers. Tagline: "Smart Team Starting With Smarter Personnel."
