Deutsche Börse admin console — screenshotFEATURED
B2B / SAAS / FINANCE2025DEUTSCHE BÖRSE
01

Admin console built in two weeks. Extended to four.

No admin tool. Four months to launch. Two weeks to design the whole thing. This is what happens when UX finally gets invited to the party.

What we got is politics.

A "simple" task handed down from HQ. Months of airtight research and edge-case evidence — all of it rejected. What finally moved it was a chance conversation with a stranger.

The Voucher Conundrum.

An engineer-built payment system, zero UX, thousands of complaints. 70 messages mapped. One confirmation page. A different man on the other side.

Promo page for a World Cup campaign.

Consumer-facing streaming product design for a multi-market African platform. Fast, high-stakes, high-visibility.

05

Token-first system. Built to be handed off.

Not a pretty Figma file. A scalable architecture using primitive and semantic tokens, W3C conventions, and real engineering handoff in mind.

The app that never shipped.

Mobile e-commerce design that died before launch. Not every project makes it. This one had good bones.

>>About

I bring design to chaos.

Over 14 years I've worked across gaming, fintech, streaming, and enterprise. I've been the solo designer, the design lead, and the person who finds out 4 months before launch that nobody built the admin console.

I work best in messy, fast-moving environments where the requirements are vague, the deadline is yesterday, and the stakeholders think "minimalism" means removing helpful UI. I've shipped products for Deutsche Börse, Wargaming, and Showmax — none of them were straightforward.

Based in Prague. Open to remote, hybrid, and on-site roles — as well as freelance and contract engagements.
