Hi, I'm Tyler Romero.

me I am an Applied Researcher and Lead ML Engineer for Groundlight, a startup focusing on multimodal question-answering for industrial applications.

In the recent past, I worked on large-scale recommender systems at Twitter, where I built all of the ML and ran the A/B tests behind the experimentally-successful yet sadly short-lived downvote button. I also researched, trained, and shipped model architecture improvements for ranking Twitter’s home timeline and conversation reply trees. And some of my work at Twitter is now open-source! Although the git-blame has been sanitized. Before Twitter, I worked as a Research Scientist building out greenfield ML projects at Microsoft.

My academic background includes a Master’s in computer science and machine learning from Stanford, and a Bachelor’s in computer engineering from Texas A&M. As an undergraduate, I performed research on novel implementations of parallel algorithms written in C / Cilk and interned as a Software Engineer at Bloomberg and Microsoft. I made a few contributions to Bloomberg’s Asset and Investment Management function and wrote Microsoft a data retrieval package for R that is still supported 8 years later.

You can reach me via email or LinkedIn message.

Website

This website is made with 11ty, Tufte CSS, and eleventufte. Custom figures are made with Excalidraw. The combination of Tufte CSS and Excalidraw to achieve a notebook-like appearance was borrowed from Simon Boehm's website, because having a visually appealing site helps motivate me to write.
