BrazilWhat I'm looking for
As a Frontend Software Engineer, I have a strong expertise in building high-performing web and mobile applications using technologies like React, Next.js, React Native, and TypeScript. My journey into tech began with a background in mathematics education, where I discovered the power of code to solve real-world problems. This transition has allowed me to contribute to cross-functional teams in various sectors, including healthcare, finance, and education.
At FIS, I led the development of BlueTicket, a comprehensive ticketing and payment solution that streamlined processes for over 20 large-scale healthcare events. I also rebuilt a mobile event app with React Native, significantly enhancing user experience for over 7,000 users. My commitment to the developer community is evident through my creation of an open-source library of animated components, aimed at elevating UI experiences.
