Hey, I’m Jarrett.
I design & build products.

Designing products since 2016. I was Design Director at Greenlight, managing up to eight designers. Now I design and ship AI products end to end.

01LivinDyno Labs client2026

I turned a meal page into a product engine.

I led menu and nutrition direction, which wasn't in scope. The menu shipped in nine days, 150+ landing pages run on it, and I built the AI chat customers order through.

Two Livin phone pages: the top of the Chicken Paillard dish page, and the menu's dish grid under the Get Started bar

I built a gift app around taste, not catalogs.

Solo, in open beta. I curated shops instead of products, because a shop is already a taste signal.

Valet ads rendered from the website's own components: plan cards and birthday lines for Mom, Dad, Grandma and friends, each on a field from that person's interests

03Level UpGreenlight Financial2021–23

I made financial learning a game tweens would play.

Kids who finished a lesson were 5.4× more likely to set a goal, and families who played retained 3 points better.

Code is the source of truth now. The tools I keep are the ones that make it easy to get code in and out, fast.

An open-source visualizer for exploring Spotify data through album covers, clips, and questions. It started with my own 16 years of streaming history and is becoming a tool other people can play with.
