A Portfolio Guide from a CTO Who Has Reviewed 10,000 Applicants

This is a practical portfolio guide shared directly by a CTO who has reviewed over 10,000 applicants. There is no such thing as a "guaranteed pass portfolio" or a "correct way to structure it" in this world. I will show you the reviewer's perspective: how they look at a portfolio, what they use to judge skill, and what content causes them fatigue. A portfolio is not simply about listing many items or decorating them flashily. The core of this lecture is understanding the process itself—properly organizing and communicating what problems you solved, and what you considered and chose during that process. Whether you are an experienced professional or a newcomer, this lecture will be helpful for any developer who has wondered how to organize and promote their portfolio, blog, GitHub, and side projects.
