Fullstack Web Developer

Hello, I'm

Ángel Matos

Full-Stack Web & Mobile Developer

I help businesses transform complex ideas into scalable, high-performance digital products. As a Full-Stack Developer, I specialize in crafting exceptional user experiences with React (Next.js/Vite) and React Native for web and mobile platforms.

I build robust and secure backend architectures. I design efficient APIs (REST/GraphQL) using modern environments like Node.js (Express) and enterprise ecosystems like Java with Spring Boot, backed by databases like PostgreSQL and MongoDB.

I ensure the quality and reliability of every delivery through automated testing (Jest, Supertest, Playwright, JUnit) and CI/CD implementation with GitHub Actions, Docker, and Azure. My goal is to write clean, maintainable code that is ready to scale in the cloud.
