I'm a Computer Science graduate specializing in Android development. I build native Android apps with Kotlin and Java, and cross-platform apps with Flutter and React Native, handling everything from UI and navigation to databases and Firebase integration. What I can build for you: ✔ Native Android apps (Kotlin / Java) ✔ Cross-platform apps (Flutter, React Native) ✔ Firebase integration — authentication, real-time database, cloud storage, notifications ✔ Database design and integration (SQLite, MySQL) ✔ Bug fixes and improvements for existing Android apps Why work with me: ✔ Clean, scalable code using modern Android practices (OOP, View Binding, Navigation Components) ✔ Clear communication and honest timelines — you'll always know where your project stands ✔ Careful testing before every delivery Before moving into development, I worked in IT support and network analysis, so I know how to listen to what users actually need, solve problems under pressure, and explain technical things in plain language. Native Portuguese speaker — happy to work with clients in Portuguese or English. Send me a message about your project and I'll get back to you quickly. Let's build something great. less -
