I’m Raymond Del Rosario, a Senior React Native Developer with about 6 years of experience building high-performance mobile apps for iOS and Android. I’ve worked on all kinds of projects from messaging and e-commerce to entertainment, educational, and delivery apps. One of my favorite projects was building two real estate apps from the ground up and one for customers to submit issues and documents, and another for managers to oversee units and generate reports. I love taking ideas from concept to launch using React Native, TypeScript, GraphQL, Firebase, and Expo. What really sets me apart is that I focus not just on coding, but on creating fast, stable, and scalable apps that people actually enjoy using. I’m all about clean architecture, great collaboration, and delivering real results.
