I’ve finally opened public access to my Product Security Knowledge Base. It brings together and structures my experience, working materials, snippets, examples, interview prep, learning paths, leadership notes, and a wide range of insights across AppSec, DevSecOps, API Security, Cloud Security, and related areas. My goal was not to create just another collection of links or scattered notes, but a practical knowledge system people can return to in real work, learning, interview preparation, and long-term professional growth. It’s now public — FEEL FREE TO EXPLORE IT. I hope it helps people grow faster, build a deeper understanding of Product Security in practice, and maybe even open the door to new professional opportunities. I’d truly appreciate your feedback, suggestions, and thoughtful contributions. OFFICIAL LINKS FOR SHARE: OFFICIAL WEB PAGE GITBOOK
