Staff Security Engineer · Anti-abuse, account security & application security

I keep bots and account thieves away from players.

Staff Security Engineer, previously at Microsoft and now at Riot Games, focused on bot mitigation and account takeover prevention. Founding engineer of Riot's Player Security team, where I work on antibot, account security and account remediation for players across Riot's games.

Product-minded: the problem I solve for players matters more than the stack I solve it with. I take the growth of the people around me seriously and have mentored many software and QA engineers.
