I'm Dimitar, design generalist based in Lisbon

At Yokoy, I designed an industry-leading invoice platform from zero in 90 days. I used hyper-lean UX approach: testing with one user and implementing changes immediately to hit 8 design cycles in record time.

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

The payoff was a successful launch and a product that eventually contributed to a 9-figure acquisition.

After the launch, the next bottleneck came into focus. Custom enterprise workflows were originally hand-coded by our CTO.

To solve this we ran the process in reverse: I skipped Figma and we went straight to a code prototype to validate the logic fast. Only at the end we polished UI.

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.

We found our users needed to handle urgent tasks while traveling. But many doubted we could bring such a complex design to mobile.

I tested two mobile solutions, and the winner was a horizontally split design inspired by Google Maps which kept the invoice image constantly visible so users could reference it against the OCR-captured data for quick verification. This enabled managers to handle 80% of their core tasks from a phone.

Before joining Yokoy I co-founded an agency serving clients like World Health Organization and International Water Association

I also designed landing page for Top Eleven, most popular football manager game in the world with 150 million players

Before UX I used to work as Art Director in advertising with brands like McDonald's, Philip Morris International and Avon

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