A career timeline built from the work history available for this profile.
Senior Software Development Engineer (Ad Supply)
I was the technical lead for a team of six engineers. I designed and implemented a migration of our ad rate limiting service to a modern architecture, and in the process improved the availability of the service to four 9s, while also reducing its infrastructure cost by half. I recovered up to 1 million ad opportunities a day by bypassing a bottleneck in our cache service's DynamoDB accelerator cluster by implementing in in-memory cache. I also founded the CDK Bar Raisers SIG to raise awareness and expertise around CDK at Twitch. We offered expert code reviews to any CDK developer and provided feedback to the builder tools team that owned many shared CDK libraries on their roadmap.
Dec 2022 - Jan 2024
Software Development Engineer (Ad Supply)
After a serious security breach at Twitch, I created the technical strategy for migrating all ads org services out of our legacy account in onto the modern Fulton service platform I had helped develop on my previous team. I personally designed and led a team of 2-4 in the implementation and migration of these services with zero downtime and no major incidents.
Mar 2021 - Dec 2022
Software Development Engineer (Builder Tools)
I was an IC on the backend builder platform team (developer experience). I contributed to many projects, including the onboarding workshops and documentation, a new service creation CLI, and the standard VPC library used by all services at Twitch, which I later ported from CloudFormation to CDK.
Jan 2018 - Mar 2021
Software Development Engineer (Ads)
I migrated ad revenue reporting jobs and the revenue configuration (CPM, etc.) out of our monolithic Ruby-on-Rails app and into to two Python services deployed with Elastic Beanstalk. One of these services, the ad-revenue-service, ran successfully in production with almost no modification for 6 years.
