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 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 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.
