About This Wiki

AI Skills Wiki is a bilingual (English / 中文) reference covering the skills that show up again and again in job postings at leading US AI companies — production RAG, AI agents, LLM evaluation, the modern TypeScript/Python stack, and the enterprise compliance world (FedRAMP, SOC 2, NIST).

Why this site exists

Each entry started as a real gap analysis: comparing a 20+ year software architect's résumé against current openings at companies like OpenAI, Anthropic, Cohere, and Scale AI, and writing down — precisely — what was missing and how to learn it. The entries are the study notes, published in wiki form so they stay useful to others walking the same path.

What you'll find in every entry

• A plain-language definition of the skill
• Why AI companies ask for it (with the job-role context)
• The key concepts interviewers expect you to know
• A concrete, project-based learning path
• Curated official resources — no content farms

Who maintains it

The site is maintained by Alex Liu, a senior software architect and full-stack developer based in Minnesota, USA, with two decades of experience across finance, healthcare, and e-commerce systems. New entries are added as new skill gaps surface from ongoing job-market analysis.
