LessonAI
An AI system that turns a teacher's raw vocabulary list into a standalone, interactive English lesson — generation, exercise scaffolding, and delivery in one pipeline.
Selected work
Projects
Things I've built end to end — shipped products, research prototypes, and open-source tools. Star counts and repositories are on GitHub.
xrag
Retrieval-augmented generation over arbitrary documents — ingestion, chunking, reranking, and evaluation wired into one reusable stack.
Spelling Correction Vietnamese
Vietnamese spelling error correction with a Seq2Seq model, handling the diacritic and tone-mark errors that generic spell checkers miss.
IDCard-OCR
End-to-end recognition of Vietnamese ID cards using a custom CenterNet for corner and field detection paired with a Seq2Seq attention recognizer.
AI Interior Design
A web product generating interior design ideas from a photo, built on a generative pipeline of SDXL with custom LoRA, ControlNet, and IP-Adapter, served asynchronously through Django, Celery, and Redis.
AoDai LoRA
A Stable Diffusion LoRA finetuned on thousands of images of the traditional Vietnamese áo dài, capturing silhouette and fabric detail that the base model reliably gets wrong.
