Award-winning builder going deep into complex problems
to design → ship software inside orgs and beyond

10+ years in tech, designing web and mobile apps across education, finance and AI, from early-stage startups to big corporations like LEGO, where I've shipped data-heavy internal tools used in 40+ countries.

Context

Design ran on founder assumptions, in a team skeptical of design-driven process. No user research, specs breaking between Figma and code, and no way to tell whether a feature solved a real problem.

Outcomes

Kicked off user research: Beta, Ideal Customer Profile, and Continuous Discovery

Grew a beta program to 400+ users and led design through public launch

What I did

Kicked off user research, standing up beta, ICP, and continuous discovery practices so the roadmap ran on evidence instead of guesses.

Drove UX improvements across the app: designed core features like bulk swap, trigger orders, and Earn, redesigned asset management with accordion interactions, and reworked navigation, discovery, and charts.

Kicked off the design system: 20+ core components redesigned and shipped under a single source of truth, so specs stopped breaking between design and build.

What changed

Research revealed the real user base was more crypto-native than the team had assumed, which refocused the roadmap and the onboarding.

Product decisions moved from assumption to evidence, with user research influencing prioritization.

Design shipped faster and more predictably, with feedback loops and syncs that kept design, product, and engineering aligned.

Context

Commercial planning ran on offline spreadsheets and meeting-dependent alignment, with no product discovery behind it and a team that didn't yet share a definition of design. Leadership had no single source of truth for the plans markets were committing to.

Outcomes

Ran the product discovery that defined the strategic planning tool from zero

Ran cross-product research across two different tools, 33 users in 50 countries, to define how they should integrate

Shipped the tool to all markets, replacing weeks of manual spreadsheet consolidation with one shared source of truth

What I did

Ran product discovery from scratch: 20+ interviews with senior leaders across the Americas, Western Europe, and Global, plus focus groups and workshops across markets.

Sharpened the patterns into a validated problem framing, moving the team from a house of assumptions to a clear point of view on what was worth building.

Designed and shipped the tool through every phase of deployment to all markets, sustaining momentum through stakeholder and PM transitions.

Organized the first hackathon in the B2B area, with 60%+ of participants wanting to keep building after it ended.

What changed

The tool deployed to all markets, replacing 650 working days of manual spreadsheet consolidation.

Product decisions moved from assumption to evidence, and user engagement rose once discovery ran the roadmap.

The prototypes became the team's single source of truth through the engineering handoff and POC phases.

Was brought in to lead research across the neighboring trade tool, running a 33-user study across 50 countries to test whether merging the two tools would cut the double data entry markets were stuck with.

My international career taught me one thing: speed.

Hackathons are how I keep up with the world over a weekend.

Invest in private companies before they go public

Onchain exposure to private companies. Put up collateral, mint a synthetic asset that tracks the company's value, and stake it.

Context

Retail investors had no on-chain way to touch private, pre-IPO companies, the asset class where most value now compounds before anyone can buy in. When I joined, the whole thing was a whitepaper and an anonymous DAO. I joined to design and build it all up, product, brand, and governance.

What I did

0 → 1 DeFi product shipped

Designed and shipped a working synthetic-assets dApp with deposit, mint, and stake user flows.

Art-directed the Ice is Melting, Frozen Ghosts collections, and the metaverse story it lived in, end to end.

Onboarding journey map

Building is what pulled me into every layer of design: branding, UX/UI, product, service design.

And what made me teach and mentor 1,000+ people at Ironhack, Echos and ADPList.
