Wong

I build teams and products that turn ambitious ideas in AI into useful experiences for millions of people.

Solving hard problems, building durable teams.

I’m passionate about scaling engineering organizations that deliver innovative products used by millions. My work spans AI products, growth, infrastructure, machine learning, messaging, and full-stack product development.

Across Perplexity, Otter.ai, Meta, and startups, I have led organizations through rapid growth, foundational platform work, and the launch of entirely new product experiences.

From zero-to-one products to global-scale systems.
