🛡️ About Me
I’m Jorge Cerezo Dacosta, a 22-year-old cybersecurity researcher and bug hunter from Madrid, Spain; passionate about web application security and ethical hacking.
With over 3 years of experience in the field, I specialize in finding security vulnerabilities through bug bounty programs. HackerOne is the platform where I’ve dedicated most of my time.
I have discovered security flaws in major companies across different countries and sectors, including Amazon, Salesforce, Google, Epic Games, Inditex, PayPal, GitHub, TikTok, and many more - totaling over 400 companies.
My favorite type of bugs are those involving business logic flaws that require creative thinking and deep understanding of application workflows.
🎓 Education
I hold a Bachelor’s degree in Computer Engineering from Universidad Politécnica de Madrid, where I completed my thesis on applied web security. You can find it here.
