Transforming ideas into apps is what drives me!
#Development #Mobile #ReactNative

I’m a mobile developer with 1 year of experience, specializing in React Native and Firebase, working on creating complete applications from concept to publication in the app stores. My focus is on performance, design, and scalability, always striving to deliver intuitive and high-impact solutions.

During this period, I participated in the development of my own and collaborative projects focused on commercial, educational, and automation applications, applying best practices in modern mobile development and integration with cloud services.

My experiences include:

✔️ Development with React Native (Expo, Expo Router, Navigation, Reanimated, Gesture Handler);

✔️ Modern TypeScript and JavaScript;

✔️ Integrations with Firebase (Auth, Firestore, Storage, Remote Config, Functions);

✔️ Integration of RESTful APIs and real-time data manipulation;

✔️ Publishing apps on the App Store and Google Play;
✔️ Interface design and prototyping with Figma;
✔️ Styling with TailwindCSS, Styled-Components, and iOS (Glassmorphism) and Android-inspired design;
✔️ Automation and CI/CD with EAS Build and GitHub Actions;
✔️ State management (Context API and custom hooks);
✔️ Basic backend with Node.js, Express, and PHP;
✔️ Payment and subscription integration (RevenueCat);
✔️ Cloudflare Workers & R2 for hosting and automated deployment;
✔️ Good practices for clean code, componentization, and SOLID principles;

✔️ Agile methodologies (Scrum, Kanban) and version control with Git.
