I’m a React Native Developer with 5+ years of experience in mobile app development, helping companies build fast, scalable, and revenue-generating iOS and Android products. 🎁 Message me for a FREE consultation. I’ll review your idea, prototype, or existing codebase and recommend the best next steps. ⭐ I bring 5+ years of practical mobile app development experience across both iOS and Android, covering early-stage products, startup MVPs, and larger applications built for continued growth. ⭐ As a React Native Developer, I design and deliver production-ready mobile applications using React Native Expo, Expo, React Native Firebase, React Native WebRTC, React Native iOS, RevenueCat, and TestFlight. ⭐ My experience as a full stack developer also extends beyond the mobile application. I work with Node.js, Python developer workflows, TypeScript, AWS, GraphQL, and REST API integrations. ⭐ I build scalable React Native Expo architecture supported by React TypeScript AWS cloud integrations, real-time functionality with React Native WebRTC and JsSIP, subscription monetization through RevenueCat, and reliable TestFlight beta deployment workflows. ⭐ I approach mobile app development with both a technical and business-focused mindset. I review user flows, identify possible product bottlenecks, and make architecture decisions that support future growth. ⭐ I communicate effectively with UI UX designers, copywriters, product managers, web developers, front end developers, backend developers, Flutter developers, and other specialists involved in the product development process. I offer a free brief and product audit to start. If you already have a prototype or existing codebase — even better. We move faster from there.
