About me
I am a software developer focused on building end-to-end web applications, with a solid understanding of every layer of the system—from user experience to backend logic and the architecture that supports it. I work efficiently, optimizing time without compromising quality, and I adapt quickly to new environments and technologies. I currently specialize in web development using Next.js on the frontend and NestJS on the backend, building robust, scalable, and well-structured applications. I also have experience working with SvelteKit and developing mobile applications using React Native (Expo) when the project requires it. I have strong technical foundations and continuously improve my skills, adopting new tools and approaches to develop faster and more effectively. I use artificial intelligence as a strategic support to accelerate workflows, validate solutions, and improve productivity, while always maintaining high standards of code quality, readability, and maintainability.
