AI Engineer
AI Engineer focused on LLM applications, Agentic AI, RAG and backend systems that connect models, data, APIs and modern web interfaces.
Available for AI projects
About Me
Applied AI with backend depth.
I build practical AI systems across data processing, knowledge retrieval, model inference, logging and API integration. My strongest work is in education-focused AI products and LLM/RAG systems.
AI/ML Intern, Lab AIoT
Worked on Vietnamese speech processing modules, model inference APIs, audio preprocessing and deployment documentation.
LLM and RAG systems
Designed retrieval pipelines with parsing, chunking, embeddings, vector search, grounded answers, tool execution and audit logging.
Backend AI delivery
Built FastAPI services, database integration, background jobs, role-based workflows, dashboards and production-oriented logs.
Skills
AI, backend and product stack.
Core stack from the resume: LLM applications, RAG, AI agents, FastAPI backend systems, vector databases, ML models and modern frontend delivery.
