Retec · Founder
Suite of smart tools for everyday work. OCR (live at
ocr.retec.vn) converts images and PDFs
into Vietnamese text, including handwriting and formulas, extracts the information you need, and exports
to Word or two-layer PDF. PHOTO (coming soon) edits text in photos and scans while keeping the original
font, ink color, and layout. (Python, OCR)

AI Agent Automation Framework
Multi-tier automation platform where AI agents autonomously plan and execute
multi-step tasks — web search, data extraction, scheduled pipelines, and formatted report delivery
via email. Designed around a modular pipeline architecture with PostgreSQL as the state store.
(Python, PostgreSQL, LLM, Cron)

RAG-based Personal Knowledge Assistant
Local Q&A system over personal notes and documents — designed with a
retrieval layer (FAISS vector index), embedding pipeline, and LLM inference layer as distinct
architectural components (Python, Embeddings, FAISS)
