From 2012 to 2022, I worked on a range of products and systems touching nearly every aspect of the end-user experience. It started with Who To Follow, and soon after, me and a few team-mates "co-founded" a new product called MagicRecs. I was the lead engineer for MagicRecs and helped it become the largest growth driver for Twitter. In early 2017, I started to focus on a project called SimClusters, which enabled a quantum leap in Twitter’s ability to model user interests and spin up new recommendations products effortlessly. Other important initiatives included company-wide priorities such as Topics, Personalization, and some specific projects in Health. At Twitter, I was fortunate to work with wonderful colleagues who trusted my ability to rise to new challenges. I held the role of a Principal Software Engineer at the time I left, having received multiple promotions during my time at the company.
