Profile: https://flows.cv/dominicktwitty

I work on exabyte-scale storage systems at LinkedIn, enabling faster and more efficient storage of nearly all LinkedIn data, from member-facing photos and videos to the datasets that power machine learning.

My previous role was in scaling PubSub infrastructure at LinkedIn, including improving the ability to push trillions of messages per day to thousands of topics. In particular, I helped LinkedIn transition to Northguard, a next-generation streaming system.

I started my career at Google in cross-exchange ad serving, where I worked to select 1 ad from millions of candidates, several million times per second. I then moved to App Ads, where we used machine learning to match the right apps to the right users for every Google search query.

My personal technical interests include machine learning, low-level optimizations (go Rust!), compilers, and distributed systems.
