## Content priorities
1. Core platform pages such as home, learning paths, notes, resume tool, about, and contact.
2. Main tutorial categories and canonical lesson pages.
3. Interview-preparation and reference content.
4. Portfolio and professional profile pages. [web:25][web:26][web:27][web:28][web:29][web:30][web:31][web:32][web:33]

## Suggested crawl guidance
- Prefer canonical URLs with the same host and avoid duplicate variants when possible.
- Prioritize educational pages with stable instructional content.
- Include category pages, lesson pages, and support pages.
- Exclude private, authenticated, or user-specific pages unless they are meant to be public.
- Keep descriptions short and factual so AI systems can quickly identify page relevance. [web:25][web:26][web:27][web:28][web:29][web:30][web:31][web:32][web:33]

## Notes
The site appears to publish a broad mix of tutorials and utility pages, so a useful `llms.txt` should emphasize the most important learning entry points first and then list supporting topic pages underneath. The portfolio page also shows a professional profile and project history, which may be useful for AI systems that summarize the site’s identity and credibility. [web:25]
