About Danh Phan
AI Engineer & AI Automation Developer
AI Engineer and Automation Developer specializing in LLM applications, autonomous n8n workflows, Computer Vision/OCR, and tailored management systems.
With a strong engineering background and hands-on experience delivering enterprise automation, I bridge the gap between cutting-edge AI models and everyday business operations. My philosophy focuses on pragmatic engineering: choosing the simplest architecture that reliably solves the problem, putting human verification on high-risk AI decisions, ensuring data sovereignty, and providing comprehensive documentation and handover.

Guiding Principles
The engineering standards and ethical commitments behind every deployed solution.
Pragmatic Scope
Solve the core business bottleneck first. Avoid over-engineering systems that can be accomplished with reliable, deterministic logic.
Right Level of AI
Do not insert generative AI where simple rule-based validation or deterministic scripts are faster, cheaper, and 100% accurate.
Human-in-the-Loop for High-Risk Output
Whenever AI parses sensitive financial, medical, or legal documents, flag low-confidence predictions for fast human review.
Data Sovereignty & Privacy
Private customer data and internal records should never leave your controlled cloud or VPS without explicit consent.
Complete Documentation & Handover
Every project includes clear architectural diagrams, operations runbooks, and team handover sessions.
