AI-powered video creation for advertisers.
I lead product design at TikTok, currently building Symphony — our AI creative studio for advertisers. I've designed its tools from the ground up (image-to-video, text-to-video, avatars, an editor) and wired them into one ecosystem. Around 2 million videos have been made with it so far.
Before this, I led 0→1 design at Rippling — a performance suite that hit $5M in its first year and earned a US patent. Studied HCI at UC San Diego.
Outside work, I'm usually chasing good light and better tea — the rest's in the photos below.
My camera roll is mostly lavender fields, film photos, and afternoon tea somewhere with a view. My passport's not far behind — South of France to Shanghai this year.
