PackPerks extends Burger King SmartBin return flow from a one-time deposit refund into an app-free loyalty loop. The core problem was that users could return a cup and get reimbursed, but had no strong reason to come back, track progress or choose rewards. I explored reward concepts, tested QR versus NFC, mapped user trust issues and designed a QSR-focused web app and dashboard around clear rewards, cup progress, direct-refund fallback and measurable return behaviour.

bol.com sellers face repeated compliance work because the same manufacturer, document and safety data is often entered product by product. I mapped this as a data-model problem, then designed a supplier-facing compliance workspace around reusable data tiers, AI-assisted prefill and clear task flows. The final concept included a dashboard, saved-data library, product compliance pages, conflict resolution and submission tracking.

Card games tend to feel too complex for casual play or too shallow for serious players. As founder of BekFlip Games, I designed Billion Battles end-to-end: rules, mechanics, artwork, packaging, and the Kickstarter campaign. A fast-paced RPG card game balancing combat with deck-building, packaged for global shipping. 150% funded on Kickstarter in 3 days, shipped to 20+ countries, earned 'Project We Love' status, and validated demand with 100+ backers as a solo founder.

Researcher and founder Luciana Duarte needed a bilingual portfolio and research hub to communicate her work on sustainable fashion and Amazonian value chains to journalists, companies, and academics. Over a year, I built a bold, editorial web experience with rainforest-referencing typography and structured sections for consultancy, press, publications, blog, and a PhD-thesis countdown. A living platform balancing activist messaging with editorial clarity. Launched and active.

Philips' Digital+ app for expectant parents had inconsistent UI, fragmented flows, and no shared visual language. With developers and senior UX designers, I ran user testing, stakeholder interviews, wireframes, and prototype iterations. A coherent component system, clearer hierarchy, and refined visual quality across the experience. 178% higher user satisfaction in Philips' official usability tests; three redesigned ad placements now programmed for launch.
