PRODUCT TASTE
=
CLEAR PRODUCT.
Tools alone don't make a great product. Someone still has to decide what should be built, how the experience should work and how it should feel. I combine senior product judgment with sharp visual craft — so the work moves fast without feeling rushed, generic or unclear.

05 /Questions
THINGS FOUNDERS ASK ME.
I work with founders, product teams and growing companies — mainly in fintech, AI, SaaS and startup contexts where the product is complex and needs senior design judgment.
