At Caixa Econômica Federal, I audited the design system across five active products, documented 16 missing and 12 broken components in Figma, and reported the findings through the team’s research channel. That work led to the missing components being built.

At GIM Digital, I rebuilt Abrace’s donation portal by fixing its slow load time and broken mobile checkout before staging a migration that preserved recurring-donor records. The launch had zero downtime, a PageSpeed score above 90, and a 47% increase in monthly active users within three months.

In my freelance practice, I took NatureFinance’s COP30 Bioeconomy Challenge platform from signed contract to launch in two weeks by focusing on three launch-day functions. It drew more than 30,000 visits over seven months. I also use AI early in discovery to widen the options, then judge what holds up against real constraints.
