I currently lead an AI Engineering team at Amazon Web Services (AWS) that helps customers build and use AI agents. In addition to our work with customers, we build open source AI projects like Agent Plugins for AWS, MCP servers for AWS (the fastest-growing open source project in Amazon’s history), and infrastructure tools for AWS AI services like Amazon Bedrock and Amazon Bedrock AgentCore.
Previously, I worked in R&D at The New York Times, exploring how AI and emerging technologies could advance journalism. I helped digitize the paper’s full archive back to 1851, built systems that generated question–answer pairs from articles (published at EMNLP 2022), and prototyped ways to make video a core Times experience. I also launched an academic research program connecting the Times to leading AI institutions and labs.
Before the Times, I co-founded NationalField, a data and analytics startup that helped political and nonprofit organizations manage distributed teams and measure field performance in real time. After its acquisition by EveryAction (now Bonterra), I led product design—reimagining a SaaS suite used by major advocacy and fundraising organizations worldwide.
Earlier in my career, I helped build technology infrastructure for President Obama’s 2008 campaign, one of the first in U.S. history to deeply integrate data, software, and grassroots organizing at national scale.
