What I'm looking for

I seek roles building scalable, production mobile apps (Flutter) within collaborative, Agile teams, with opportunities for technical leadership and impact.

I am a Software Engineer with 5+ years building production-grade mobile applications using Flutter and Dart, delivering solutions for enterprise clients like BMW and Stone Co. I specialize in state management (Bloc/Cubit), mobile architecture, comprehensive testing (bloc_test, mocktail), CI/CD (GitLab CI, Fastlane) and backend integration.

I have led cross-functional teams and end-to-end product development across hybrid and remote environments, architecting mobile and backend systems (Python/Django), optimizing performance, and maintaining high code quality through testing and Agile (Scrum) practices. I am client-oriented, communicate effectively with global teams, and am currently pursuing a PhD in Electrical and Computer Engineering.
