What I Ship
Production AI systems with fixed scope, clear deliverables, and written handover. No hourly billing.
LLM Workflow Automation
Replace 10-hour manual processes with AI pipelines. Content generation, data processing, ops automation — built to run without you.
RAG Systems & AI Chatbots
Chatbots trained on YOUR docs. Vector search, embeddings, retrieval-augmented generation. Not a wrapper — a real system.
Internal AI Tools
Custom AI tools for your team: document processing, report generation, smart search, auto-classification. Integrated into your existing stack.
No-Code + Custom APIs
Connect AI models to your existing tools via APIs. Works with n8n, Zapier, Make, or fully custom endpoints. You pick the level of control.
Built by Me, Live in Production
This portfolio site isn't my best work — my Vietnamese platform is. Same stack I build for clients.
nguyenxuantai.com
