Essiel V.

Senior Mobile App Developer | Flutter, React Native, Swift & Kotlin

💪 I can do what AI can do and I can also solve the problems AI can’t. I help startups and businesses build high-performance mobile applications that are reliable, maintainable, and ready to scale. Many mobile apps become difficult to improve as they grow because of poor architecture, inefficient state management, and weak backend foundations. I build applications with clean architecture, optimized performance, and production-ready integrations so they remain stable as new features and users are added. Flutter is my primary framework for building cross-platform iOS and Android applications, but I also have extensive experience with React Native app development. My background in native mobile development (Swift and Kotlin) allows me to handle platform-specific requirements, native integrations, performance optimization, and complex mobile challenges when needed. What I do: - Develop native iOS and Android applications (Swift, Kotlin) - Build production-ready Flutter, React Native, Expo applications - Integrate Firebase, Supabase, REST APIs, and AI/LLM APIs - Implement payments with Stripe and in-app purchases - Optimize app performance, reduce unnecessary rebuilds, and improve responsiveness What I focus on in every project: - Clean, maintainable code built for long-term growth - Smooth user experiences under real-world usage - Backend integrations designed to support future expansion Recent project focus: - Startup MVP development - AI-powered mobile applications (chat, automation, API-driven features) - Scaling and refactoring existing Flutter, React Native, Expo applications - Performance optimization for production apps - Native mobile features and platform-specific integrations Whether you are launching a new mobile product or improving an existing application, I can help you build a stable foundation that performs well today and continues to scale in the future.
