Mid-Level Flutter Developer
"With seven years of experience in technology, expertise in Flutter, and a solid foundation in web, backend, and SRE, I have established myself as a Mobile Specialist focused on Flutter. I hold a Technical Diploma in IT (ETEC) and am currently pursuing a degree in Computer Science (IFSC). I work as a Flutter specialist, serving as the technical authority for scalable architecture decisions, code structuring, testing tool selection, and advanced integration with native code (Kotlin and Swift) for performance optimization. Beyond development, I am deeply involved in technical leadership and mentoring. I excel at guiding teams through complex challenges and recently led a 48-hour Flutter bootcamp, where I trained new talent for the job market. My track record includes delivering high-impact projects, ranging from robust mental health apps for veterans with native integrations to the software powering Cinemark's self-service kiosks. In addition to my corporate experience, I work as a freelancer and develop my own projects, constantly challenging myself and staying up-to-date to achieve my ultimate goal: leaving my mark on the world through my creations :)"
Career
UEEK Agência Digital
Mid-Level Flutter Developer
I developed systems exclusively using Flutter, serving as the technical lead for the mobile division. I was responsible for defining project architecture, managing GitHub repositories, structuring and documenting CI/CD pipelines, and establishing new testing processes and continuous improvement initiatives. I also led team development—training new members and implementing coding best practices—conducted code reviews, and managed app publishing and maintenance on the Google Play Store and App Store. I played a key role in the evolution and scalability of the ValorNet project, a white-label mental health mobile app for army veterans. I implemented complex features, including smartwatch integration (health and exercise data), group audio and video calls, push notifications (Firebase), and VoIP (APNs). I also developed native code (Swift, Kotlin) to handle background calls, local storage, and live streaming systems. In this project, I solidified my technical leadership by mentoring developers, proposing solutions, and managing automated deployment workflows. Daily interaction with clients and international team members also enhanced my technical and formal English communication skills. I also worked on the Fito Agrícola project, focusing on layout improvements and bug fixes for an app built using a layered architecture, Riverpod for state management, and OpenStreetView map integration. Additionally, at UEEK, I served as an instructor and mentor for the “UEEK Connect” Bootcamp, introducing the Flutter ecosystem to beginner developers. Over the course of a month, we built a mobile travel log app from scratch using Clean Architecture, Riverpod, Supabase as the backend, and OpenStreetView map integration.
