Antti is an IT entrepreneur, a PHP enthusiast, and an OSCP certified penetration tester 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 and design CTF challenges and puzzles, reverse engineer binaries, 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.
