GEO Next.js TypeScript React Schema.org llms.txt Lines Courses

GEO Engineer — I build systems that make brands visible to AI. Generative Engine Optimization (GEO) is the discipline of structuring digital presence so that large language models accurately represent, cite, and recommend entities.

  • Educational Platform — 35 free courses (387 modules) on AI, GEO, SEO, Python, and development
  • Multi-LLM Orchestration — 5-LLM pipeline (Claude, GPT-4o, Gemini, Perplexity, Groq) for content generation
  • llms.txt Advocacy — promoting the llms.txt standard for AI discoverability
  • Entity Consistency �� machine-readable entity representations using Schema.org and knowledge graphs
  • B2A (Business-to-Agent) — how organizations should present themselves to autonomous AI agents
