About
I am a software engineer, researcher, and designer. I develop better interactive software that empowers individuals. My work combines ideas from several fields—programming languages, graphics, machine learning, and systems. Notable projects include:
- Percival, reactive notebooks for exploratory data analysis.
- Rustpad, self-hosted online collaborative code editor (1M+ downloads).
- Crepe, compiled Datalog language in Rust, used by cloud security systems and compilers.
- FastSeg, real-time semantic segmentation models for autonomous vehicles.
- Set with Friends, online multiplayer card game (20M+ pageviews, 600K+ users).
I currently live in New York where I am building a startup, on a leave of absence from Harvard. Previously, I worked at Prosper Robotics, Convex, Jump Trading, Scale AI, and Nvidia. I also wrote a physics book, published math research, and made graphics tutorials used by thousands.
At Harvard, I was a distinguished teaching fellow for upper-level computer science classes, and I found my home in music. I play viola in the Harvard-Radcliffe Orchestra and chamber music groups. I was a YoungArts award winner in classical music, served as principal viola of the Texas All-State Symphony Orchestra, and have been invited as a soloist with a professional orchestra.
Competitive Programming
I am a top-ranked competitive programmer. I won two gold medals representing the US at the International Olympiad in Informatics (IOI), placing 7th globally. I also ranked highly in the USAMO and USAPhO, and I competed on Harvard's championship-winning ICPC team.
I have written and tested problems for large national and international programming competitions, including the following:
- USA Computing Olympiad (USACO)
- National Olympiad in Informatics Philippines (NOI.PH)
- PWSH Programming Contest
- HackerEarth CodeStar Contest
My advanced algorithm and data structure library is available here. If you are looking for tutoring, I have previously taught recorded courses with Alphastar Academy for motivated students aiming to perform at a high level in programming competitions.
