Math Engineering Lead @ Duolingo

I am currently working on making Duolingo the best place to learn math!

We use start-of-the-art AI techniques (code as output, code agents, MCP, etc.) make high-quality math education accessible to all.

Learning Scaling Engineering Lead @ Duolingo

I transformed the Learning Scaling area, a group of teams working on content creation, from slow human-driven processes to highly automated, technology-first, AI-powered systems. I drove the area's strategy, doubling the area's engineering headcount, and led the area to exponentially increase content output multiple years in a row. Check out our 2024 Q4 shareholder letter for more information.

Learning Infrastructure Team Lead @ Duolingo

Learning Infrastructure was the first infrastructure team in a product area at Duolingo. We were responsible for addressing the area's technical debt and redesigning our content serving architecture. This "infrastructure team" model was replicated across Duolingo due to its success.

I spun up and grew the team from 3 to 7 engineers over 2 years. I managed all team members and successfully coached one engineer to replace me as team lead as I moved into area leadership.

Learning Assessment Team Lead @ Duolingo

Learning Assessment was my first foray into team leadership and management. This team was responsible for measuring the efficacy of Duolingo's teaching methodology for both internal and external purposes. We ran complex studies, built internal assessment tools, and shared our findings with the world. One of our journal articles was the most viewed article in Foreign Language Annals.

The team started as just me and an assessment researcher, meaning that I had to work on everything from performing high-stakes data analysis to building automated pipelines for running studies, to designing novel methods of evaluating Duolingo's efficacy. I loved it! Over time, we grew to five members across 3 functions.

Individual Contributor @ Duolingo

I started at Duolingo as a backend engineer. Throughout my time as an IC, I focused on our learning systems, especial learner progress and lesson generation.

Carnegie Mellon University - Undergrad

Honors: ACS Scholar

I started at CMU as an undeclared science major, but quickly found out I wasn't quite as good at Physics and Chemistry as I thought. I found my home in the computer science and philosophy departments. In my first "intro to programming" class, 15-112, my Arduino harp project was voted best in class, and that was it.

I also found a love for academic research. I completed a CS senior thesis and published my first conference paper in Educational Data Mining, which has been cited 50 times.
