I am a mobile and web developer based in Tulua, Colombia. I build cross-platform mobile applications with Flutter and React Native, and web applications with React and Node.js. My work covers the full cycle: requirements analysis, UI implementation, REST API integration, state management, testing and deployment to the App Store and Google Play. I also develop backend services with Node.js, integrate third-party APIs and databases, and maintain existing codebases. I have professional experience as a developer at Smartinfo and currently work at SaaSCol. I write clean, maintainable code, communicate clearly in Spanish and English (B1), and deliver on agreed timelines. Available for hourly or fixed-price projects at 15 USD per hour.
