Available to hire
I’m Samuel Obinna, a Flutter developer with 6+ years of experience designing, building, and shipping production mobile apps across fintech, edtech, and social platforms. I specialize in real-time communication (WebRTC), live video streaming, and scalable state management architecture (Riverpod, GoRouter). I own mobile codebases end-to-end, from authentication and payments to complex live-class and video infrastructure, while collaborating closely with backend and design teams.
I’m passionate about delivering robust, testable mobile code and delightful user experiences, and I enjoy collaborating with cross-functional teams to ship features that scale.
