About

It's been now more than 4 years since I started my journey in freelancing and cybersecurity. I've been fortunate to work with some of the biggest companies in the world and learn from the best in the industry by doing bug bounty hunting. I've also been able to build my own products, tools and applications to help me in my journey. Also ranked top 40 in YesWeHack, the European leader in bug bounty.

    Onyx

    Remote

    Onyx was an AI when AI wasnt cool. It was a chatbot that could answer questions and help you learn about the world. It was also a way for me to make a plugin system for my work and my stuff.
