About Ewir

Hello, I'm Ewir Rodríguez.

I combine a solid technical foundation with a focus on user experience.

- I have experience leading applications that serve over 100,000 users, ensuring your product can scale without breaking.

- I implement the latest mobile architectures like Kotlin Multiplatform and modern declarative UI to ensure your app is maintainable long-term.

My Specialized Services:

- Modern and Cross-Platform Android Development (Kotlin / Jetpack Compose): I create visually stunning and fluid native interfaces using Jetpack Compose. Additionally, thanks to Kotlin Multiplatform (KMP), I can write business logic once and share it between Android and iOS, accelerating development without sacrificing native performance.

- High-Impact Web Development: Corporate websites and SPAs optimized for Core Web Vitals. My focus on robust architectures ensures minimal loading times and a smooth user experience.

- Hybrid Mobile Apps (React Native): The ideal solution to launch on iOS and Android simultaneously with a single codebase, optimizing your budget and development time.

- Premium iOS Native Development: For when your project demands maximum performance and seamless integration with the Apple ecosystem.

Ready to take your project to the next level? Let's talk about your goals. I can bring modern technical solutions from day one.
