About Me

What I work on

I'm Vo Phu Thinh (Võ Phú Thịnh), an AI engineer in Ho Chi Minh City, working at HPT Vietnam Corporation in the AI Center of Excellence. I build chatbots and assistants that answer from a company's own documents.

Most of my work is RAG with Qdrant, tool calling through MCP, and voice or text chat over WebSockets. I spend as much time on retrieval, chunking and testing as on the model.

Highlights

Lyly, an executive AI assistant: voice and text over WebSockets, hybrid search in Qdrant, memory with mem0. 2nd prize at HPT's Enterprise AI Competition.
HPT D-DAY 2025 chatbot: answered 850+ attendee questions in one day at Pullman Hanoi, using the official event data.
HIH ("Sóc Dò La"): a pipeline that summarizes industry news and posts it to Viva Engage. 8,500+ impressions, 3rd prize.
Copilot and automation: prompt and grounding work for Microsoft Copilot, plus 10+ workflows in n8n and Power Platform that cut manual work by about 60%.

I'm open to AI engineer roles where I can own a project from prototype to production.
