What I'm looking for

I want to own end-to-end product design—from brand and design systems to UX/UI and prototypes—partnering closely with founders and teams to ship fast and scale real user value.

I’m a Product Designer with 8+ years of experience helping startups with fundraising, go-to-market, and end-to-end product design. I’ve founded and bootstrapped my own startup to 125K+ users across 30 countries while maintaining 5-star ratings on the App Store and Play Store.

In my most recent work, I founded and bootstrapped Doctor Wise, owning branding, marketing, product design, and business operations. I built a 5-star UX experience and an affiliate system that acquired users at near-zero marketing cost—backed by strong reviews in Brazil.

I also create product foundations quickly and strategically. For The Registry, I built the full design foundation (brand identity, design system, prototype, and pitch decks) in under two months to support the founder’s fundraising and launch. Previously at Hypha, I owned the design system and designed the marketplace UI and liquid staking experience end to end—work that the CEO cited as key to traction.
