I am based in Madrid, Spain, and I’m available for hybrid or remote roles. I’m a Flutter Engineer with 5+ years of experience delivering scalable cross-platform apps using Flutter, Dart, MVVM, Cubit, BLoC, Clean Architecture, modularization, dependency injection, Firebase (RemoteConfig, Crashlytics, Analytics), REST APIs, secure storage, geolocation, background services, and native Android (Kotlin) and iOS (Swift) integrations. I work with CI/CD pipelines and automated testing (unit, widget, and integration), always focusing on performance, code quality, refactoring, accessibility, and maintainable architectures. I also have backend knowledge that supports API design and end-to-end integration. I’m passionate about mentoring developers and collaborating with cross-functional teams to deliver reliable software. My experience spans healthcare, IoT, and mobility domains, and I enjoy refining architectures, improving efficiency, and enabling teams to ship features confidently.
