CHALLENGE

Design a system users trust with high-stakes moments while the underlying AI capabilities shifted underneath us every few weeks.

GOALS & SCOPE

End-to-end experience from first touch to power use: flows, system design, motion and the metrics framework to prove it worked.

TEAM

Led product design in partnership with research, data science and engineering pods from concept through launch.

Leon does the groundworkResearch, audits and systems thinking before any pixels move.
Keeps you in the loopOpen files, weekly rituals and decision logs the whole team can follow.
Ships the detailsMotion, states and edge cases polished to production quality.
Product in the wild

Reflections & insights
What this story taught me — the notes I’d hand my past self.
01 — SPEC TO SHIP
Ideas turn into shipped product
Work lands with engineering as specs that answer questions before they’re asked — flows, states and motion, documented.
02 — SYSTEMS FIRST
One decision, reused everywhere
Patterns are built once and propagated — tokens, components and guidelines keep the pods shipping the same product.
03 — MEASURED
Design tied to outcomes
Every release pairs with a metrics plan; wins and misses feed the next cycle instead of a slide deck.

01 — TRUST IS THE PRODUCT
Earn it in the first minute
AI features live or die on trust. Every surface shows its reasoning, exposes its data use, and makes undo effortless.
02 — DEFAULTS DO THE WORK
Design the 90% path
Most users never touch settings. The default experience is the product — so it gets the most iteration, not the least.
03 — MOTION IS MEANING
Animate to explain, not decorate
Every transition answers “what just happened?” — state changes are narrated by movement before a word is read.
04 — SHIP TO LEARN
The prototype is an argument
Real usage beats opinion. Small, instrumented releases settle debates that meetings never could.
Between the pixels
Moments, outtakes and behind-the-scenes — the parts that never make the case study.
