Another report showed how college-prep services shared student data with online advertisers .

Developed and maintained the data infrastructure for an ongoing investigation into for-profit schools in California. The work involved continuous data scraping, cleaning, and analysis to support reporting .

Co-developed a high-level, Apache Spark-like language for querying network telemetry data. The language was designed to compile down to the data plane of programmable switches, allowing for network monitoring and security tasks to run at line rate .

Co-authored a large-scale internet measurement study that sent millions of address queries to Internet Service Providers. The project aimed to create a more accurate map of broadband availability across the United States, highlighting gaps in coverage .

Collaborated on an end-to-end system for monitoring live network traffic. Sonata allows network operators to ask complex questions about packet statistics using a high-level query language, with the system providing answers in real-time by leveraging programmable hardware .

As a software engineering intern, I built the back-end infrastructure to allow third-party plugins to run securely on top of the core Pure Storage system architecture .
