Born and raised in Long Island, NY. Now studying computer science & math at Yale. My interests include full-stack development, machine learning, bioinformatics, and neuroscience.

Email is the best way to get in touch with me.


I got my start with iOS development in 2010, making a couple (long-defunct) games to get my feet wet.

At WWDC in 2013, I crossed paths with Rohan Kapur, and we started building a debate platform Contra. Many years and several iterations later, the app now has a modest but devoted user base; the app is still functional today, although as of 2018 I have begun to shift my focus to new projects.

Along the way, I found my way to the field of machine learning. Rohan and I started A Year of AI in 2016 to document our learnings. A handful of machine learning projects are still available on my GitHub.

In 2017, I enrolled at Yale University. At Yale, I’ve been involved with the following groups:

  • Yale Daily News: I co-lead the web development team, where we are now in the process of planning a ground-up redesign of our website and internal tools to modernize our newsroom. I also wrote about dinosaurs once.
  • Computational Linguistics at Yale: With the CLAY lab, I work on trying to gain insight on the linguistic abilities of neural networks. Most recently, I’ve been working on our stack-augmented neural network model.
  • YDriving: We program miniature self-driving cars using computer vision and machine learning techniques. Our exploratory work with these cars is now being offered as a course in the computer science department in Spring ‘19.
  • Restaurant Rescue Project: I served on the board of RRP my freshman year. We help to eliminate food waste around New Haven by bringing leftover food from restaurants around the area to shelters and soup kitchens.

In the summer of 2018, I interned at Yale startup Snackpass (YC W18). As one of five engineers at the company, I was responsible for rebuilding their backend infrastructure in Node.js and migrating away from Firebase.

In the summer of 2019, I will be interning at Butterfly, helping to build the iOS app that powers their portable ultrasound devices.
