About
I'm a data scientist currently at Meta, where I lead experimentation, causal modeling, and AI-powered analytics for consumer wearables across Reality Labs. Previously at Deloitte, I built generative AI systems, fraud detection models, and customer analytics pipelines across TikTok and Apple. I also like building apps and personal projects in areas I'm interested in — whether it be stock analysis or getting better at blackjack. In my free time I like to golf, snowboard, and bake delicious home pizzas 🍕
Projects
Blackjack-101
A full-featured blackjack game and educational tool with web and mobile clients, built as a monorepo. Teaches optimal blackjack strategy by guiding players through correct decisions — when to hit, stand, split, or double down — helping users build intuition and get better at the game.
EarningsLens
A stock analysis web app for tracking earnings events, company fundamentals, and macro indicators. Integrates Financial Modeling Prep, Finnhub, and FRED APIs with a Supabase/Prisma backend.
Earnings Reaction Model
A machine learning pipeline for predicting post-earnings stock price movements, built on 15,000+ S&P 500 earnings events and a focused study of 35 AI Infrastructure companies. Combines FMP price & earnings data, SEC EDGAR 8-K press releases parsed by Claude AI (extracting guidance tone, management confidence, and AI-demand signals), and FRED macro indicators. Includes two comparative analyses: a broad S&P 500 statistical baseline and a sector-specific study of how the AI boom has changed earnings reaction dynamics.
