About

Nathan Kumar

I graduated with a Bachelor of Science in Computer Science from the University of Arizona, focused on data engineering, machine learning, and building systems that make sense of large-scale real-world data.

Currently I'm at Meta as a Data Engineer in Reality Labs, based in the Bay Area. My most recent work includes architecting production data pipelines processing event-level data for 30M+ Meta Quest users, including automated anomaly detection for conversion rates and cohort-level behavioral analysis.

Before that I spent a year at Leidos as a Software Engineer on the Geospatial Intelligence team, contributing to the Commercial Joint Mapping Toolkit (CJMTK), a full-stack platform serving 5k+ monthly users at the U.S. Department of Defense. At the University of Arizona, I built ML-powered real-time occupancy forecasting for the Recreation Center using the Google Vision API and Scikit-learn, shipped as a live student-facing dashboard.

Outside of work I build things I find interesting — right now an iOS app that uses LLMs to convert unstructured personal health logs into structured, queryable data.
