I'm an AI-driven software engineer specializing in Retrieval-Augmented Generation (RAG), multi-agent AI systems, and knowledge graph engineering. I design and implement end-to-end AI pipelines that balance faithfulness and relevance, turning complex data into actionable insights. I love building secure, scalable AI applications and optimizing multi-database architectures (vector and graph) to deliver reliable AI outputs. Most of my work centers on LangChain, LangGraph, CrewAI, Llama3, Milvus, and Neo4j, with deployments on AWS and a focus on MLOps. I’ve led automated RAG pipelines processing large document sets (e.g., CVEs, CWEs, CyBOK) and integrated hierarchical knowledge graphs to boost performance and trust in AI systems.

Work Experience

AI Engineer at CREST
May 1, 2025 - September 29, 2025
Built fully automated RAG pipeline processing 150K+ CVE, CWE, CyBOK documents. Designed data pipelines for scraping, entity extraction, and chunking into Milvus (vector database) and Neo4j (knowledge graph) databases. Developed multiple RAG architectures (VectorRAG, GraphRAG, HybridRAG) for different complex domains. Built experiments using Llama3.3 and GPT-4; evaluated RAG system performance with RA-GAS. Boosted RAG performance by integrating hierarchical knowledge graph insights, achieving Faithfulness 0.97 and Answer Relevancy 0.96 for the software security domain. Built MLOps pipelines and deployed the RAG system on AWS (S3, Lambda, API Gateway, ECS, Bedrock).
Principal Software Engineer at Freelance, Vietnam (Remote)
December 1, 2024 - September 29, 2025
Maintenance and development of an in-house microservices ERP system using Java/Spring Boot, NestJS, React, and PostgreSQL. Built CI/CD pipelines with GitHub Actions; deployed the system with Docker/Kubernetes on AWS. Developed reusable libraries to streamline internal backend workflows.
Principal Software Engineer at ZamoTech
January 1, 2022 - September 29, 2025
