I design complex B2B, cybersecurity & fintech products as a senior product designer and two-time founder.

At Yokoy I designed an invoice platform from zero in 90 days. I tested with one user at a time and implemented changes immediately, completing eight design cycles.

It was a gamble: some changes actually made the experience worse. But constant monitoring meant we caught and reversed them quickly.

The product launched successfully and later contributed to a 9-figure acquisition.

After the launch, custom enterprise workflows were still hand-coded by our CTO.

To validate the logic quickly, I skipped Figma and we built a code prototype. We polished the UI once the interaction worked.

The end result was a visual, drag-and-drop builder with pre-set templates. This reduced onboarding from months to hours and unlocked $2M in ARR.

Users needed to handle urgent tasks while traveling. We needed to bring a complex workflow to mobile.

We tested two mobile solutions. Users preferred a horizontally split design inspired by Google Maps, which kept the invoice visible beside OCR-captured data for quick checks. This enabled managers to handle 80% of their core tasks from a phone.

Before joining Yokoy I co-founded an agency working with clients like the World Health Organization to digitize and democratize access to safe drinking water standards and improved the International Water Association website loading time by 1200% while achieving 99.99% uptime.

I also designed a landing page for Top Eleven, the world’s most popular football manager game, with 150 million players. Since then, Nordeus, the studio behind Top Eleven, has joined Take-Two Interactive—the publisher behind Rockstar Games and Grand Theft Auto.

Outside of UX I love exploring the intersection of technology and play through 3D animation and interactive art projects.
