I design and build with AI for early-stage founders who need to go from idea to product in weeks, not quarters.
Currently at Counter HealthScroll01 / Manifesto
I don’t just design screens. I help founders decide what to build, prototype it with AI and ship it.

Intuition forms bold bets. Research and tests validate them before you scale.
What works pre-PMF: short cycles, design debt on purpose and talking to users more than you design.
