Hi, I’m Pedro Rafael Barrios, a passionate Web and Android Developer with a strong focus on building clean, fast, and user-friendly applications. I specialize in modern JavaScript and backend technologies like Node.js, with experience in PHP and CMS platforms. Over the years, I have developed responsive websites, mobile apps, and full-stack solutions for clients and startups.
I enjoy working on freelance projects, collaborating with teams, and engaging in remote opportunities. When not coding, I love optimizing SEO strategies and enhancing digital marketing campaigns to help businesses grow their online presence.
