Hi, I’m Everton Greeff Leopoldo Fiegenbaum, a Mobile Software Engineer specializing in cross-platform apps with Flutter and native Android. I design, build, and maintain mobile solutions that integrate RESTful APIs, real-time features, and offline data storage to support diverse operations from field work to kiosks.
I enjoy collaborating across disciplines to deliver polished UI/UX, reliable back-end connections, and scalable code. Based in Brazil, I thrive in multidisciplinary teams and continuously learn new tools to shipping high-quality apps.
