I'm Arun Nagarathanam, and I've taught more than 200,000 learners on Udemy over the last 10 years.

I started with search.

In 2010 I built a tech news blog from nothing to 17,500 visitors a month, with no budget and no team, and that is where I learned how people find things online.

My AI SEO and AI GEO courses now rank first in Udemy search for "SEO" and "GEO".

Today

Most of my work runs on AI agents and Agentic AI workflows.

Where one simple task used to take me days, I now finish 35 to 40 tasks a day with Claude Code, Codex, Hermes, Grok Bot and the system and routines I built around it.

My courses teach that same way of working, so you build real things while you learn.

What I teach now:

- Claude Code and agentic AI: building, deploying and running real apps

- Exam preparation for the Claude Certified Architect certification

- AI SEO and GEO: getting found on Google and recommended by ChatGPT, Perplexity and Gemini

- PowerPoint presentations made with AI

I answer all my learner's questions and assignments myself within 8hrs window. If something in a lecture doesn't make sense to you, ask in the Q&A.
