What I'm looking for
At GRUPO SBF, I work as a Software Engineer. Before that, at Dafiti, I implemented app deep links for Android and iOS, increasing app users by 20%, and automated team feature tests with Maestro.
At N26, I redesigned Kotlin onboarding endpoints, cutting latency from seven seconds to one, and implemented Flutter two-factor authentication used by more than 300,000 users. I also created a document-resubmission feature that improved conversion by 70% for users whose registration was denied because of photo issues.
I created the zzCar Flutter app from scratch and led its MVP development, reaching 50 subscribers in the first month. I’ve also shared my work at The Developers Conference, speaking about building a digital bank for gamers with Flutter in three months.
