At Multibet, I worked on product design for a B2B betting platform and white-label operations, building multi-tenant experiences with Product and Engineering. I structured the Design System for Supernova’s international operation, also applied to Play4tune and Multibet, with 87 screens and more than 200 components across three tenants.

At Cassino.bet and 7K.bet, I worked on UX/UI for two betting brands with distinct audiences. I led the Cassino.bet sportsbook redesign, revising flows and interfaces based on benchmarking; one month after launch, sports bets rose from 3% to 10% of total betting volume, according to a database query.

My projects include a mobile gamification system for Play4tune, bringing five modules and 15 screens together in a single-entry hub, and three mobile minigames with a shared purchase, play and reward flow. I also created and implemented Instituto MAIS’s digital presence, from visual identity and interfaces to website launch.

Earlier, at Instituto ESPE, I supervised graphic and digital design production and led a four-person team. I implemented Kanban to organize requests and standardized communication pieces to maintain visual consistency.
