With several years of experience building scalable mobile and web applications using Flutter, I am confident that my background and technical expertise make me a strong candidate for this role. Currently, I work as a Senior Flutter Developer at BHP, where I helped build a new enterprise-grade system across Web, iOS, and Android using Flutter.
