Projects
A collection of AI and machine learning projects that showcase practical applications of modern deep learning techniques.
VietStoryLens
AI-Powered Historical Landmark Recognition using an Agentic RAG pipeline with LangGraph. Combines CLIP embeddings, FAISS retrieval, and GPS-based Haversine re-ranking to identify landmarks and generate historically grounded narratives. LotusHackathon MVP winner.
AI-Powered Fungi Detection
Hybrid ConvNeXt + Transformer model achieving 97.7% accuracy in fungal species classification. Led a 4-member team at the Olympic AI HCMC Competition, automating the full data pipeline from ingestion to preprocessing.
Shrimp AI Detection & Sizing
AI-powered shrimp health monitoring and length measurement system using YOLO/RTMDet. Detects disease symptoms and measures shrimp body length in real-time for aquaculture quality control, achieving over 95% detection accuracy.
Intelligent Data Assistant
Multi-tasking Text-to-SQL Chatbot capable of navigating 62 complex schema tables. Leverages Metadata Enrichment and RAG to convert natural language into precise SQL queries for real-time farm management.
ApplyAI – AI Job Crawler
AI-powered job aggregation platform scraping 9 Vietnamese job boards with intelligent CV tailoring. Uses GPT-4o to analyze job descriptions and generate role-specific CVs via a LaTeX PDF pipeline, boosting interview rates.

TypeScriptAbout Me
AI Engineer with 1+ year of experience in Smart Manufacturing and Agentic Workflows. Winner of AI Hackathons, 4th place at Olympic AI HCMC 2025, and passionate about building production ML systems that make real impact — from Computer Vision pipelines to intelligent RAG-powered assistants.
Bachelor of Machine Learning
Began studying Machine Learning at HCMC University of Technology. Dove deep into algorithms, neural networks, and computer vision fundamentals.
Python Instructor & Outstanding Graduate
Taught basic and advanced Python to high school students while earning Outstanding Graduate of the Class of 2023. Developed strong communication skills by breaking complex technical topics into clear lessons.
Hackathon Champion
Won the PieoneDream Hackathon AI x Blockchain. Built VietStoryLens — an AI-powered landmark recognition app that became the LotusHackathon MVP. Active as Google Developer Group facilitator at DevFest.
AI Engineer Intern — ThinkWare
Executed high-precision data annotation for autonomous driving, including Object Detection and classification of thousands of objects in complex road scenes.
RAG Specialist — TURING
Designed and executed RAG evaluation pipelines measuring Retrieval Quality (Hit Rate, MRR) and Grounding Accuracy. Curated instruction-tuning datasets to improve Tool Calling reliability for internal LLM agents.
AI Engineer — Mebisoft
Current role designing AI-powered Shrimp Detection & Sizing systems (YOLO/RTMDet) for aquaculture and building an Intelligent Data Assistant (Text-to-SQL) for smart manufacturing. Reduced inference latency from 45s to <15s.
