A bit about me

I'm Bamidele Johnson, a senior mobile application developer with a focus on building production-grade apps that serve real users at scale. I work across the full mobile spectrum, from cross-platform Flutter and React Native builds to native iOS (Swift/SwiftUI) and Android (Kotlin/Jetpack Compose).

Through my work at DJH'S Studio and with clients like Soillight and Economic & Business Strategies, I've delivered end-to-end mobile solutions spanning e-commerce, safety tech, fintech, and sports. I care about clean architecture, high test coverage, and shipping code that's as maintainable as it is performant.

I'm a certified Flutter developer and MongoDB associate, fluent in English with basic conversational knowledge of Portuguese. I bring the mindset of a builder, high ownership, high accountability, and a bias toward shipping.
