• Implemented a self-serviced account reactivation flow which increased account reactivations by ~600% (roughly 1500 reactivations per day) and decreased account-related support tickets by 73%.
• Formulated and executed a migration plan for over 360 million live user images from legacy S3 bucket. Using NGINX's HTTP proxy and AWS Batch Operations, completed a full migration in 3 days with no customer impact.
• Added "spare key" functionality to authentication flows using AWS Elasticache and device cookies, so that authenticated users can securely bypass Twitch's login throttling and are protected from denial of service (DoS).
