About

A bit about me

I work on machine learning, quantitative finance, and the systems that hold them up. The problems I like are the ones where the math, the model, and the infra all have to agree.

At Amazon this summer I’m on the Long-Term Planning and Forecasting team in Supply Chain Optimization Technologies (SCOT), building the centralized Config package that all 13 engineers use to drive MOSAIC, our long-term revenue and inventory forecasting platform.

Alongside that I build Quantiv, an options-implied earnings platform on Vercel: multi-week calendar, screener, symbol pages, and a Clerk watchlist over nightly JSON, with LightGBM scoring on DuckDB / Parquet and live quotes through Upstash. Before Columbia I published single-author at the IEEE ITSC on graph-network traffic forecasting (24% RMSE win over STGCN) and built a CFD + neural-net F1 wing optimizer.
