Antti Rössi

Antti is an IT entrepreneur, a PHP enthusiast, and a white-hat hacker based in Helsinki Finland.

During the daytime, he’s leading an innovative recruitment technology company called Jobilla, where he’s mainly focusing hands-on in the actual product design and development processes day-to-day. For the night time and weekends, he turns into a white hat hacker that loves to solve CTF challenges and puzzles and to spend time penetration testing open-source software in private bug bounty programs in order to make the web a safer place for us all.

He is passionate about teaching fellow developers about software security (especially within the PHP community), and is known for concrete hands-on oriented presentations and workshops.
