At BestHR Solution, I built the backend for WordScan, an AI document-intelligence product that extracts structured data from CVs, labor contracts, and health certificates. I upgraded Gemini 2.0 Flash to 2.5 Pro, raising handwriting accuracy from 65% to 90%.
I also designed the integration between the HR platform and VNPT eContract for identity verification, signing, and contract digitisation, working with FPT and VNPT engineers. I built the company’s marketing website in React 19, Vite, and Tailwind CSS 4, serving three languages.
In my projects, I built a LangGraph agent with tool calling, RAG, and a tested CI/CD deployment, and a resumable chemistry-video generation pipeline. For my graduation thesis, I crawled more than 55K posts into a labeled Han-Nom corpus of 10K+ samples, with 98.2% mean character alignment.
