Hi, I'm Justin. A design leader, comfortable operating anywhere from vision to execution.

Excerpt from the five design principles written for the Allie v3 redesign — Patient-first always, Be opinionated about their care, Bias toward simplicity
01

Setting the vision. Driving it to delivery.

A complete reframe of the patient experience — and the vision, principles, and delivery plan that got it there.

Ask Allie introducing the SMART goals framework

03

A small change. A full-funnel win.

Patient onboarding — found the drop-off no one was tracking and lifted end-to-end completion.

Scout · AI + Little League
An AI scouting department for my son's baseball team.

A season of league-wide GameChanger data turned into coaching intelligence — pushed opponent insights, a drag-and-drop lineup builder, and an agent the coaching staff used through the playoff run.

Dayfall · dayfall.app
A memory app wearing weather's clothes.

Pick a day and a place — your wedding, a famous snowfall — and feel it again: the satellite view, the day's light, and the weather written back like a memory. 530 public days, checked against NOAA's own stations.

Dayfall · the footer
How much care a footer deserves.

How Dayfall's footer went from a blank text field to the most-considered thirty lines on the page — twelve rounds of exploration, one colour rule bent on purpose, and three failed attempts to animate three dots.

About
Justin Kodama

Good design should be invisible — not hidden, just so natural you don't notice it.

That's what I've spent twenty years building toward — products that get out of the way so people can focus on what actually matters. Most recently at Codex Health, that meant helping patients manage chronic conditions and helping clinicians scale their practice without losing the human touch. Before that at Pear Therapeutics, it meant prescription digital therapeutics — FDA-regulated software where the stakes made the craft feel worth it.

I operate across the full spectrum from vision to execution. I'm comfortable setting long-term product direction in the morning and sweating interaction details in the afternoon. I've spent years filling the space between design and product — writing PRDs, phasing engineering delivery, making prioritization calls — because the work needed it and I had the context to do it. Nights and weekends I build things end to end with Claude, most recently Dayfall, a memory app that shows you the weather on any day of your life.

I'm a Bay Area native — born in Berkeley, now living in Alameda with my wife Grace, our 14-year-old Jackson, and our 11-year-old Ryan. I've coached little league for four years, which has been one of the more unexpectedly useful and fulfilling things I've done. I'm also mid-pursuit of a 750-pound powerlifting total, which is the kind of slow, measurable goal that suits me fine.
