About

As a kid, I dreamed about inventing something, even though I had no idea what that meant. In high school I discovered programming, in grad school I fell in love with building products, and the rest has been figuring it out with people I love working with.

University of Tennessee

BS in Computer Science, Mathematics, German. Year abroad at TU Dortmund.

I grew up on Long Island, moved to Tennessee for high school, and studied Computer Science, Mathematics, and German at the University of Tennessee. My junior year, I studied abroad at TU Dortmund in Germany, which gave me a second language and a wider lens on the world.

After college, I spent three years at Sandia National Laboratories in Albuquerque, then moved to Stanford for a Masters in Computer Science. My research in Prof. Monica Lam's lab focused on platforms for mobile and social interaction. I also co-founded a mobile messaging app called ZapText through the Lightspeed Summer Fellowship.

In 2010, I joined Pulse as the second engineer. Over the next three years, we scaled from under 1 million to over 25 million users, won an Apple Design Award, raised a $9M Series A, and were acquired by LinkedIn in 2013.

At LinkedIn, I became Director of Engineering, leading teams across Feed, Learning, and content distribution. My teams built AI-driven relevance and curation systems, shipped LinkedIn Learning to millions of users, and led engineering for both consumer and enterprise learning experiences.

I then joined Magical as Head of Engineering, where I grew the team, established product tracks, pivoted the company to gen-AI, and shipped self-serve monetization. It was also where I felt firsthand how hard it is for marketing teams to get engineering support, even for work that could help them scale.

After years of building personalization and growth systems, one thing kept bugging me: AI changed the top of the funnel, with infinite creative and instant testing, but the rest of the funnel didn't evolve. Personalized ads still hit generic pages. Marketing teams rarely get the engineering support they need, so they end up doing everything manually and struggle to scale what works. Intent, momentum, and ROI leak out in that gap.

That's why I started Tailor AI with cofounders Wei Xiao (CTO) and Chris Fong, founding engineers Matt Ng and Josel Salalima, and Albert Hwang (COO). We all worked together on the same team at LinkedIn for years, so we know how to build together. We're building an AI team for performance marketers to increase revenue by identifying high-value visitors, tailoring the funnel to intent, and turning monitoring into next best actions.

Outside of work

I'm a dad to two boys, which is the best and most humbling thing I do. When I'm not building Tailor, you'll find me paddleboarding, playing tennis, skiing, biking, or losing at chess. I love coffee, bad puns, and traveling anywhere I haven't been. I still speak German, though my kids aren't impressed by it yet.
