Hello! I’m Jeremiah Ekanem, a Senior Mobile Engineer with 6+ years of experience designing and delivering scalable, high-performance cross-platform applications from MVP to production. I started my career in 2019 as a native Android (Kotlin) developer, bringing strong fundamentals in mobile architecture, performance tuning, and platform-specific optimization. I have since become proficient in Flutter (Dart), system design principles, AI-driven features, and modular architectures for long-term maintainability. I’ve led engineering teams, guided complex API integrations, monetization systems, and secure payments, delivering apps that have impacted 200K+ global users in fintech, social, ride-hailing, and Web3 domains.
I thrive in cross-functional teams and enjoy building secure, scalable mobile solutions that customers love. My recent work focuses on shipping AI-powered content moderation, crypto-to-payments infrastructure, and end-to-end encrypted messaging while ensuring robust security and delightful user experiences.
