I've built and maintained Android applications at NTT DATA, including new features, bug fixes, code reviews, unit tests, accessibility work, and delivery across multiple app modules.
At Workana and BrazilianCard, I developed mobile sales, truck weighing, sensor analysis, and POS applications. I integrated Bluetooth devices, thermal printers, NFC, payment readers, cameras, QR and barcode scanning, MySQL backends, and real-time order flows.
I bring 6+ years of Android experience in Kotlin and Java, using MVVM, MVP, MVC, Coroutines, Retrofit, Firebase, SQLite, and Material Design. Earlier frontend work with ReactJS, GraphQL, AngularJS, JavaScript, PHP, and WordPress gives me a strong foundation across web and mobile development.
