I untangle complicated problems by making them undeniable, data that reframes the brief, alignment that collapses five opinions into one, then a solution that feels like it was always obvious.

01
Find the real problem before designing
→ the wrong question wastes everyone's quarter.
02
Iterate in tight loops with real users
→ five conversations beat fifty assumptions.
03
Build systems that scale, not just screens
→ tokens, patterns, and rules a team can defend.
04
Ship with metrics, not hope
→ if we can't measure it, we shouldn't ship it.
05
Never stop improving
→ the design ships, then the work begins.

- Mentoring designers on the team and aligning UX with product and engineering through cross-functional workshops.
- Hired alongside the team for a Conversational Designer role to grow LLM design capability.
