Hi, I'm James Wang

I'm a senior AI engineer and systems architect. I've been shipping software for 23 years, and for the last three I've been putting AI into businesses like law offices, restaurants, schools and contractors.

• Now: Senior Software Engineer at QIAGEN, and part-time CTO of AAWEA, a nonprofit for entrepreneurs
• Built: 11 AI platforms, designed and shipped end to end on my own
• Focus: LLM agents, RAG, voice AI, and the guardrails that make them safe to use: permission tiers, human approval, PII redaction and audit logs
