As a mobile frontend developer, I collaborated with the team to build and maintain these features, working closely with designers, backend developers, testers, and product manager.

The "Pizza Hut Brasil - Web" project is a React-based web app for food delivery. It mirrors the mobile app, including features and business rules, complete with a responsive version for both desktop and mobile. I was responsible for transitioning between the mobile and web applications, developing features in both, and playing a crucial role with expertise in the technologies of both platforms.

"Crie Seus Posts" is a React app within a microfrontends framework. It lets users craft custom posts with Natura brand images, like social media posts. You can add backgrounds, products, and text, and download or save posts for future editing. It's fully responsive for web and mobile. I led the project, working closely with designer and backend.

The 'Betim Sem Dengue' app was one of my early React Native projects, originating from a collaboration between my workplace and the city I reside in. It aimed to enable residents to report dengue mosquito breeding sites, utilizing user location and images sent to a database for health agents' action. Developed within a tight timeline, the project broadened my React Native skills.
